If I use slow speed I could probably take a nap at the same time its so slow, but if I go medium speed and try to slow down at points, curves, etc. that my stitch size also changes. The only thing I have had an real luck with is using SID, but with a zig zag; however, this isn't always real neat on curves, points, etc. I am glad to see that others have as many problems with machine quilting as I do.
