When I use my dining room table I use a cutting board (the kind that is cardboard and folds up and is about 3X6 feet when open) on top of it. That not only protects the top of my table but also gives me something to clip my quit to. I use bulldog clips that I get at an office supply store. I lay my quilt back wrong side up on the cutting board and clip it to the edges of the cutting board so it doesn't move. I then put the quilt bat on and follow that with the quilt top. I reclip the sandwiched quilt using the bulldog clips to the cutting board and then start pinning. Since I can't fit my entire quilt usually on the table I do it in sections but the bulldog clips keep everything together while I'm working on it. I never have any puckers or wrinkles on the back using this method.
