Just wondering where I can find/buy styrene sheets?
Around here (Wichita, Kansas) the "hobby & craft stores" (Micheals & Hobby Lobby) don't carry styrene, but the HobbyTownUSA sells Plastruct and Evergreen brands--I've bought "plain" 12" X 24" sheets there before.
We also have a model Railroad hobby store that carries both brands, but nothing larger than 6" X 12".
You can find "ghetto" styrene at Wal-Mart in the form of those thin plastic FOR SALE/GARAGE SALE/ etc signs. Old CD jewel cases are good for building too.
You can usually find small sheets at either a local hobby shop or somewhere like Hobbytown USA. For bigger sheets try www.plastruct.com.
Are any of these stores near you: http://www.tapplastics.com/stores/index.html? They might have something that works for you. Check out their sheet products here: http://www.tapplastics.com/shop/category.php?bid=24&
