Found these thin sheets of acrylic (I'm guessing that's what it is) to store my stamps on. Just stamped cardstock and added stamps to the plastic. I just used glue dots to stick the cs to the plastic. You can see the dots but it dosen't bother me. I plan on storing these sheets in a clear plastic album holder. I tried first to use a binder but found it to be to bulky. So far this is working nicely. I have 6 sheets already, holding 17 sets of stamps + a handful of singles.
