side of the foam strip and a sheet of thin plastic (report cover) to the
other side, then using a 7/16" hole punch to punch all three layers. The
first batch I tried came out too wrinkly (the mylar layer) for my taste
but a little experimentation should take care of that.
That being said, I don't think I'll have time to get a batch made
before VCF. If I get my exhibit project done, I'll see what I can do.
