I use mine all the time: keep track of block sewing order, leaving up a partial quilt til I get ideas of how to proceed, just to admire my work sometimes.
I bought 2 1/2 yards of outdoor table cloth fabric at my local quilt shop (one side oilcloth the other side flannel-ish).
Tacked it with push-pins to a wall in my quilt room, flannel side out. Blocks and pieces stick to it. I straight pin on heavy pieces.
Works perfectly and alot cheaper than those my friends made.
