Turning barrels into columns- advise wanted
*advice* I meant... wow, I speller so weller...
I have a bunch of great, straight-side cardboard type barrels I want to turn into dungeon columns, but I'm coming up short on inspiration for cheaply doing so.
Ultimately I'd like them to look like "castle" stone columns, and I've been debating carved foam, but foam board is sort of hard to bend around a round surface- even if you cut the stones individually and stick them to the sides. I've also been debating some kind plaster coating with the grout lines carved in that, but I'm skeptical of its adhesion unless metal lath is applied first and skeptical of its overall finished appearance.
Anyone ever pull this off?
