Also use at least a 90/14 metallic or top stitch needle. These are sharper and have a larger eye to accommodate the thread and guide it through the stitching process.
Teri, I'm running into another problem. I confess this was occurring a bit for the first
hundred or so windows, but not too often--the thread is still fraying above the needle. BUT I tolerated it b/c I was using a 90/14 sharp/quilting needle, (actually, used a bunch b/c I kept changing them...) and didn't have any topstitch needles at home. Finally got out to the shop, got some topstitch needles, and now the fraying is WORSE...It's as if the top of the eye is just sharp & cutting or wearing into the thread
Is this likely a result of the zillion layers of fabric? Is there a solution?
