I know a lot of guys have cut gaskets from computer mouse pads and it works OK. Here's one made from "hobby foam." A piece for one gasket was $1.49 at a local craft store.
Major advantage is that hobby foam is closed cell. It doesn't absorb water. It cuts clean with a laser too. I'm disappointed that the woman who cut these for me is not the least bit interested in making any more. The laser cutter is/was her husbands. There may be issues. :-( In any case, they work out great. So if you know anyone with a laser cutter, you may be in luck. If not, a sharp hobby knife may do a fair job.
