Guess I'm really the far out quilter. I, too had problems with tucks when I first started quilting on my machine. Now. I use cotton crochet thread and baste. Use a large curved needle. Start in the middle and go to one side with inch long stitches. Turn and do the same thing from the middle again. I stay on one side of the quilt until it has been basted. When that side is basted, rows about 4 inches apart, I go to the other side and use the same method..If there is a tuck, cut the basting and remove a couple inches, spread the tuck and then use a small amount of thread to hold in place.
Bind before removing basting stitching.
I have some small tucks, but nothing that doesn't disappear when washed. Yes, It's a lot of work, but if it works and you don't want to spend the money on charity quilt, it is worth it.
