Hey, don't know if it's already fixed but on my Brother I put the tension wheel thingie between 4 and 5, never had a prob. And I assume you know you put the wire on that silver colored thing and not the plastic one?
I have a stupid question but do you maybe have a pic of the skirt inside out? I want a bubbleskirt sooo bad and can't figure out how to make it with the tuts that are already on here. *beggy beggy please* I'll love you forever!;)
