Things I learned in Class


Oliver helped me unpack from my trip, and has grown since I was away!  I think his fur is getting a little longer too, oh no....  We were so enjoying the very short crewcut style he had at first. 

He has spent this week following me around, first in love and astonishment that I came back home, then in glee and joy, and now he is doing sneak attacks and flying out of nowhere to land on me.  Usually he likes to attack a knee or ankle, but occasionally he lands on my head.  I have a few needle holes in me from these attacks, scars of an ecstatic young cat.  He naps when he can take no more excitement.

What did we learn in our class last week?  Many things, some new to me, some the old familiar discoveries made by students as we progressed through a variety of free motion skills.

One woman said the best thing she learned was to have the quilt move freely, and that was accomplished with a Supreme Slider from Pat LaPierre at http://www.freemotionslider.com/

This tool is invaluable for smooth quilting and even stitches, but be sure and tape even the self-stick ones to the bed of your machine, with at least one piece of tape to the machine itself, not the surround.  Plexi surrounds tend to move in class and then the Slider moves, and you are quilting through it along with the quilt.  Not good for needles.  Or the Slider.

Lower the feed dogs when you use a Slider.  The repeat movement if they are "up" can create a dome around the opening that can be permanent and ruin the Slider.

Another thing that is so important is how the thread is positioned on the machine for the best possible delivery, stitch, tension, no breaking needles or thread. 

Larger cones or spools need to be horizontal so the tension is accurate.  Another good option is a cone thread holder.  One student had one, but not the spindle for the thread cone.  The result?  More problems than one could imagine.  As soon as we had one with a spindle and it was set up properly, perfect stitches.

Many times the thread winds around the little end caps that hold a spool on the horizontal spindle.  My advice?  I never use the end caps and I have never had the thread fall off the spindle.  There is no chance of the thread winding around and getting caught, causing tight tension or broken thread or needles or everything. 

I fixed many thread pathway "issues" and then quilting can progress smoothly.  If you have to stop constantly with problems your quilting will suffer.  Being able to have confidence in your machine and the setup for quilting lets you quilt with freedom and you will improve dramatically.

Thread color was such a big quagmire of indecision.  The only way you will know what looks right on the fabric you are quilting is to try quilting with the thread on a small swatch/sandwich first.  The days of putting a spool of thread on the quilt and saying YES!  are over.  Since I began using fine #100 silk for quilting, all preconceived ideas of color went out the window as I began to explore what worked.

Yesterday I quilted some samples of a new design for a handout and used bright fuschia silk thread on deep brown/purply/mottled fabric and it looked great.  Brown or purple or eggplant also looked fabulous if you want this design to be background and recede around a focal point.  Your thread color choices determine what happens to the visuals in a quilt. 

I also discoverd that most people do have one "better" side for feathers, and it is usually the left side.  Some could do the right side of a vine better than the left, but this was not common.  Work until both sides look acceptable, then quilt the same thing horizontally, at an angle, upside down, to increase your skills.

Batting does make a difference.  Not only in ease of learning a design, but in the final result.  We used wool batting for the extra pouf and dimension, and also were able to flatten backgrounds with more dense quilting. 

Leaving areas of puff showcases your designs and draw the eye, creating great visual dimension.  Do not quilt the life out of your quilt. 

Stencils can work for you!  Many who used them had delightful results, a beautiful design and their own freehand work surrounding it or complementing it.  The gingko stencil was particularly lovely. 

Thread tension changed with the pilot. Many times the way a person moves hands changes the proper tension to bad tension, tight threads.  When I quilted at the machine, changing no settings, the right hand movement and stitch length let the tension setting work, do the job, and create lovely stitching.

Larger erratic stitches made for too-tight tension, and diminished any puff in the design.  The correct stitch length for the thread type resulted in perfect tension.  It also needed tweaking for the type of design.  Long soft curves might work at a tension of #3, whereas close small frothy bubbles (in photo below) needed a tension of #2 for the stitches to be perfect.

Remember to reset tension on electronic machines each time you power up.

Smooth, even hand movements are key.  That is one thing I can't help you do.  You have to acquire the mental discipline to keep hands moving smoothly and evenly to achieve those beautiful stitches and smooth designs. 

If you have to lift hands to move them to another area of the quilt, stop the machine, move them, take a brief break for your eyes by looking up and re-focusing, and then begin again with the needle up.  Try to avoid"walking" your hands over the surface of the quilt as you run the machine.  Many do not realize this is a bad habit until I point it out.

Try and quilt a bit every day.  By the end of our 5-day class improvement was amazing and noticeable. 

Yesterday I quilted for the first time in a week, and it felt wonderful.  I also discovered Oliver can now sit on the back shelf of my sewing cabinet and stare at the moving needle and the quilt and become totally mesmerized, almost in a trance. 

Obviously he has never seen this before and is entranced with it.  He has quickly discovered sitting on quilts, sleeping on quilts, sleeping under quilts, attacking quilts, but now he likes to see them being quilted.

Keep quilting  - your work gets better every day!

This and That

The leaves, above, are printed on a sheer crinkly fabric that I placed on black so the design would show more clearly. I like it. It is an old blouse I never wear, and while I was packing it up for a donation box I loved the great leaves.

I am always noticing quilting motifs in everything, and with some tweaking this one would be great. Now, to sit at my machine and play with this a bit. It might make it, or it might end up on the cutting room floor.

I've had so many emails about silk thread and how to make it work in various machines. Usually it's wise to lower the top tension a bit, maybe a lot, and use a fine cotton in the bobbin and it will work very well. Do a small adjustment at a time, maybe half a stop, so if it is set at 4, go to 3 1/2 and quilt a bit and see what it looks like. Sometimes it needs to go much lower, depending on the machine. Always check the back stitches and the tension there too.

In my last class we had two machines that had very loose bobbin tension. If I held the bobbin case up by the thread it fell. It should feel like it is going to fall to the floor but doesn't. We adjusted the bobbin tension, a bit at a time, until it felt right, then tried it in the machine. Success! Perfect stitch.

There was one that was incredibly tight, and we loosened it and it worked perfectly afterwards.

If you have "fear of bobbin tension" syndrome, and are concerned about adjusting it yourself, take it in for a little field trip to your dealer if possible and have them show you, check it, get the right information.

I have used #100 silk thread by YLI on several models of Berninas and they all take it a bit differently, but in the end, perfectly. In my last teaching trip to Phat Quarters in Galena, IL I used a new Bernina 730 and it worked absolutely perfectly at the default upper tension setting with silk in the bobbin as well. Once you get the hang of how your machine and your thread get along you will know exactly what to do, and have great success, and great confidence.

And don't forget your technician at your dealer. They see it all, know so much, and have a direct link to the mother ship.

Exciting news! I finally twisted Ann Fahl's arm and she has begun a blog. Ann is an accomplished award-winning machine quilter and art quilter who will have many thoughts and tips to share with you. I love her advice about color in her first post, and agree totally. I know I will enjoy reading her blog with my morning coffee. Her blog is http://www.annfahl.blogspot.com/

Let's welcome her to the blogosphere!

Keep quilting, your work gets better every day!

Tension and Stitch Length!

More information arrives from quilters who are dealing with new, electronic machines. Mercy recently explained her tweaking with the Bernina830 and silk thread, and she reports now that if the stitch length is set at "0," the thread tension on top gets very tight.

I have noticed on some Bernina 440's that when the BSR is used, the tension gets tighter than if a normal free motion foot is used, but of course can be adjusted down so a proper stitch is achieved.

Many things can affect the thread tension on top, even the humidity or color of thread. Dark threads may need a slightly different top tension than ecru, in the exact same thread.

In my first book, Guide to Machine Quilting, I suggested setting the stitch length to zero if you drop the feed dogs and free motion quilt. This was back in the Dark Ages when I used a mechanical machine, no brains, no sensors. Now I don't even think about doing that because my machine knows if I lower the feed dogs I don't NEED stitch length and allows them to rest comfortably in the basement, not moving at all. So I never touch that stitch length dial when the dogs are down.

On the Bernina 830 Mercy found that if she did use the zero stitch length the top tension became way too tight. If you own this machine, don't change the stitch length at all when the dogs are lowered.

All things are interconnected. Be aware.

Hope you are not slaving away too hard here in the US where we have our big Thanksgiving holiday on Thursday. I am hoping to get in an hour or so of quilting today on some ideas I've had before I forget them, and take a break from cleaning and polishing, shopping for food, cooking.

Keep quilting! Your work gets better every day.

Silk Thread on Bernina 830


Note:  Updated info I've received tells me that Bernina dealers/technicians are trained and  can help your 830 handle fine threads like #100 silk.  The newer machines have been updated as well.  If you have any issues at all, contact your technician. 

Machine quilting with YLI #100 silk thread is beautiful, exquisite. Sometimes though we have to adjust the machine to get the best result, and all machines get along with this thread a bit differently. Recently I heard from Mercy, one of my advanced students, at http://tropicalapplique.blogspot.com/ that she is the proud new owner of a Bernina 830, and has been trying to quilt with silk that was so successful in her other Berninas, as it is in all of mine (200, 730, and new 630).

After having problems, bad tension mostly, she and her technician and folks at the mother ship Bernina discovered some tips that will help you with this thread if you have this new machine. These tips might help you even if you have a different brand electronic machine with sensors.

Mercy wrote:

"First tip - the machine is soooo smart and the thread is soooo thin that for the most part it thinks there is no thread in the machine. Well, the machine is programmed to NOT sew if it is not threaded. If you reset the machine to allow it to sew without thread, then you lose all the other features like low bobbin warning, etc.

To resolve this, hold the thread tightly with your right hand as it leaves the spool and then thread the machine with your left hand. The little extra pressure is all you need for the thread to register on the sensors. Once registered, it will be fine until you need to rethread the machine.

Second tip - for silk and decorative threads it is critical to keep the machine well oiled. I usually clean and oil my 440 whenever I refill the bobbin thread. However, this machine's bobbin has a much larger capacity - more than double - and the silk is so thin you can sew for quite awhile before you run out of bobbin thread. You must stop and force yourself to do maintenance based on sewing TIME even if you do not need to replenish bobbin thread.

Third tip - the tension has to be PERFECT. If it is just a LITTLE bit off then the top will loop or eyelash just a bit every 5th or 6th stitch. If it is off by any more than just a little bit then the bobbin thread does not come up at all and the top thread breaks."

Thanks so much Mercy! I think this advice might work too with this machine and YLI Wonder Monofilament thread.

It is terrific when quilters send me vital information like this so I can share it here, and you can discover yourself what works best in your own machine and situation, and of course, always contact your dealer if you have problems or need advice. If any of you have more information, please share via the Comments.

Susan sent me the comment that there is a special/extra guide behine/under the white device that comes out to thread the machine. It's supposed to be used for fine or slippery threads to help the threading process. Bernina technicians know about this guide.

I agree about the maintenance based on time, rather than only when the bobbin thread runs out. I clean and oil the hook and bobbin area every day I quilt right at the beginning of my session. If I quilt steadily for 3 hours, I do it again.

Silk thread leaves a bit of a waxy debris in your machine so it is vital to clean it, and a bit of oil is also good. Check the top thread pathway as well, and swab out any sticky linty stuff that remains.

Run the machine, with no thread in it, quite slowly at first and perhaps more gunk will surface and you can swab that out gently with a cotton swab. Finally, run a clean dry swab over the metal parts in the bobbin/hook area to get any leftover oil, thread the machine, run it slowly and quilt with it on a sample to work out any leftover oil. I love this time as this is when I play and come up with exciting new ideas for designs.

Be very light handed and careful when cleaning/oiling your machine. Follow your technician's advice and check your owner's manual. My Berninas hum, and keep humming, and I take great care of them so that they do.

Keep quilting! It works out the oil.....and keeps your quilting zen going strong.
