Oh, and no matter which method you choose, you always want to bring the bobbin thread to the top at the beginning and secure it along with your top thread. This will prevent knots and thread nests underneath.[/quote]
Wish I had known to do this when quilting my GD's quilt for Christmas. I wound up with several "rat's nests" on the bottom. Of course' the top thread kept breaking which didn't help. It was the first quilt I had ever quilted and I wasn't happy with it. I'm going to have her send it back and redo it. It got the the stage where finished was better than perfect. :)
