Making Cut-Cards at Home, Some Questions......

[dabluebery]

Basically because I have nothing better to do with my free time, I want to try making cut-cards for my home games using a sheet of plastic and an exacto knife.

The cut-cards I get from casino supply places are pretty flimsy and sometimes slightly transparent, so I'd want to use a thicker grade of plastic.

Does anyone with a micrometer handy or some familiarity with plastic thicknesses have an idea what kind of sheet I should buy to do this?
