I have the foam insulation boards and have duct taped 1 and 1/2 together to make the board 6'x 8'. I also have one that I cut down and it is 6' x 6'. I don't put any fabric on mine because I use them to sandwich my quilts. It is so much easier than getting down on the floor or trying to reach over a wide table. I always have all four sides of my design boards full because I am usually working on one or two BOM's and if they are where I can see them I get right to work on the blocks when I receive them!
