Judi, I'm contemplating the bobbin washers but double they're available locally. May call around on that today.
Jitkaau, I'm using the single plate & still having all this trouble. Ugg!
Battle Axe....love your name, but feel like I'm insulting you at the same time! A bernina just isn't in the budget for me!
