I've been using this method for over a year now and love it. My quilts have never been flatter and honestly it's now so much easier to quilt (because they are so flat). I spray baste and pin. I have two sets of three boards, a long set for king/queen and a shorter set for twin and smaller. Got the nice guys at Home Depot to cut them for me. I do roll my batting too. I used to hate basting quilts, this method makes it so much easier. I'll add that I press and starch before rolling on the boards. This lets me start stop when I need to, as it's easy to leave and it won't get wrinkled! I use my dining room table. With leaves it's just a tad short for a queen, but the board method lets me easily slide side to side too. I've done at least 16 full sized or larger quilts this way, and i no long hate basting quilts together. PM if you need more info, I believe I've got an imgur album showing how I did a queen sized quilt with the boards.
heres a link to one of the pictures.
