I'm all over art that doesn't involve paint and a brush--because I'm terrible at that sort of thing--which is why I LOVE this project. No paint; just tape! The secret to getting the effect of tumbling blocks is in the 60 degree cuts of the decorative medium, namely, 3 different colors/patterns of Duct Tape. After cutting the strips of tape, then it's just a matter of assembling them in the tumbling block pattern on a pre-purchased canvas. Although, a primed piece of cost-effective MDF could work too. (I'd probably pass on using plywood or particle board because of their rougher surfaces.)
