Great card stock in mail.
Lately I have been getting a lot of advertising flyers and postcards printed on card stock, and it is a really great modeling material. I have used it to make pallets for applying CA glue. The stuff has a plastic coating on it, so even the thin stuff does not soak in.
Lately I have even been using it as card stock for material that goes into the project. The plastic coating makes it prime and paint very nicely. I used to hoard a supply of old IBM punch cards, but this stuff I seem to be getting almost every day in the mail is even better than punch cards- the plastic coating seems to be thicker and glossier. Thanks, advertisers, I appreciate your contribution to my modeling materials!
