Queen size years ago - this time around, big lap robe - 72x80. Scrunch and work from the center out. Never have more than half a quilt to your right. I have two machines side by side so I have a large slippery surface. I used to use the ironing board, but slippery is better. Hmm, I wonder about putting vinyl from JA's on the board. It works well on the machines. FMQ is easier than SITD. You stay in one area longer so less alligator wrestling. Though I have to say, I haven't wrestled with this one and it's 72x72. Is it the plastic? I've not used it before.
