I use the board method for sandwiching and just LOVE it. I even added my own "feature"; I covered my boards with flannel so that the quilt top and backing don't slip around on them when I start to wrap. I've made a set of 12' boards and have done quilts 11' wide using this method. It's very accurate and makes things so much easier to handle! By the way, I spray baste with 505 instead of pin or thread basting. It goes pretty fast and the quilt sandwich holds together just fine for FMQing on my domestic machine.
