I've also notice a lot of you talk about stretching your quilts out on the floor to sandwich them together. So I thought I'd let you know how I do it. I bought 2 of the cardboard fold up cutting mats years ago at one of the fabric stores. They measure 72" by 36". I place them side by side across my king size bed and use extra long straight pins to keep them from moving around. Then I can stretch the backing across them using straight pins stuck through the cardboard and into the bedding. I do the same with the batting and top. Then I can use safety pin to baste with. Once they are all together like this I just remove all the straight pins and roll up my sandwich until I'm ready to quilt it. I have done some really large quilts this way by basting what I could then moving it around to do what hung over the sides.
