Its a Singer Quantium Stylist 9960. I had better luck last night and was able to so stippling on 2 practice pcs with not snaps. My husband thinks it is "user error". I hope he is right! I do use gloves and don't think I could move the fabric without them. I am using a darning foot that my husband altered to make it open toe. That alone feels so much better. I can see the stitches easier than the closed toe.
I looked at the Sulky Viscose thread but was not sure what it was...now that I know it works I might try that. I am using overlock thread which seems linty.
Fingers crossed today is productive!
Thanks for all he suggestions!
