I'm still pretty new to quilting, but here's what I do. I put that big huge cardboard cutting mat on top of my rolling cutting board. It measures out to be about 60". Then I lay my backing down, spray with 505, lay my W&N on top of that, then spray 505 again, then put my top on. After each piece is layed down, I smooth from the center out. I then start pinning. When the top is all pinned and I need to pin more, I can move the cardboard cutting mat over a bit and finish smoothing/pinning. It keeps me off the floor as I have arthuritis in my knees. Getting down on the floor is not a problem, it's the getting up that I have the problem with. :lol:
