Paper gaskets made with blotter paper are fairly easy to make.  It is
easiest if you have a set of arch punches but if you don't then a sharp
pair of scissors can do the trick.  I have bought blotter paper from an
office supply store in the past.  I have also used thin leather in the
past with great results.

Make a pattern that you can use to make a tracing onto the paper.  Then
simply cut out with a pair scissors.  If you plan on working on players
full time then consider investing in a set of Arch punches and a hand
rotary punch.
