What a great idea! I'm using one half of my family room for sewing right now and use the carpeted floor to lay out my blocks. But I can't leave them there long because my furry sewing assistant likes to come over and rearrange them to his liking. This folding presentation board is the perfect solution and I'm going looking for one today! Thank you for sharing.
P.S. I love the fabrics on your board in the photo. That is going to be a beautiful quilt!
