Jan 28, 2017 - DIY tree trunk using Great Stuff spray foam (found in the caulking aisle), concrete tube molds, and spray paint (Rustoleum Camouflage is best, no gloss). Easy to do but the foam is super, super sticky and I highly suggest using rubber gloves. Hold the tube on its side to form your lines and go slowly. Allow to set for at least a day before you paint them. The paint will expand if you don't allow the foam to set correctly.
