I had part of a scrappy quilt I was practing FMQing on and did not like how it turned out. I took it and folded it in half and sewed the sides, right sides together making kind of a bag. Then I hemmed the top edge. Had my sweetie cut a piece of plywood to fit it, I slide the plywood into the bag, tacked the opening closed, viola, one ironing board. It is only 2 1/2 by 3 1/2 but works great. I can iron on both sides and when it gets dirty I just take it off and throw it in the wash. I love that it is portable, I set it on a small table or at the end of my cutting table if I need room to spread out fabric. You could make any size you want.
