I have used them for several years without any problem. I started out with a 1000 that I bought online, much cheaper than the stores. I have used most for 1-3 yd pieces. I store them in the plastic totes and they work very well. I have them sorted by color and on shelves. My bolts are 4 yds and up stacked on shelves. I got most of the boards from Joanns, just by asking for the empty ones.
