If you treadle and you want to find out more about free motion quilting on your machine, check out this tutorial. I followed a lot the advice and did some free motion quilting on my old Singer 27. I was having some trouble with threads breaking so instead of a flowing design I decided to do a bunch of spirals. That way the spiral would just end when the thread broke. However, today I switched from cotton to polyester thread and that helped a lot. The poly thread seems stronger and I was able to make bigger spirals that I knotted off instead of just allowing the thread to break.
Behold my work!
It's not great, but I did it! On a treadle machine! And a machine with a vibrating shuttle, too!
Unfortunately, just as I was really going my needle snapped and the tip lodged itself in the feed dogs. The screw holding that plate is stuck tight so I'll have to wait until tomorrow and try to get my husband to help it along. Figures. But I was having a lot of fun before then, so I'm looking forward to trying it again tomorrow.
