This is my first post so I hope I put this thread in the right area, if not, admin please move it for me.
Well I have a portable Pfaff machine and it always works great except all of a sudden its doing this on the bottom of fabric (see photo). I didn't change any setting, just one day it worked and the next it didn't. I'm sure it's something easy, I just don't know how to fix it. I tried all I can think of and I'm having withdrawls not sewing lol!
Thanks in advance for your help!
