I have had much success with thread basting. I put the backing on my diningroom table (which has a cover, so I don't worry about the needle scratching the wood), smooth it out, put in the batting, smooth it out, and then put on the quilt top. I work out from the center, taking big stitches in an outward spiral. then, to get to the edges that are lying off the side of the table, I just roll one side up and scoot the undone part onto the table. I have found that the thread does not allow the fabric to shift like pins do, and I have had some problems with pins ripping holes in the fabric or tangling up the thread I am quilting with. So far, no billowy or bunchy problems with this method!
