Sometimes I get those puckers because I can't keep from pulling..........I have to almost tape my hand to my chair at times. It just wants to "help" move the fabric along. I'm working on two baby quilts right now for my niece, she just had her second baby of 2008 on Christmas Eve and since she had the first one while Roy was still in hospital I never got 'roundtoit. I just know that one of them is going to pucker and I'll end up taking out part of it.
Good luck, Carol, I'll hold crossed fingers for you, k?
Hugs,
Sharon
