This type of affordable wall art is made using vinyl electrical tape. Yep, remember that vinyl electrical tape is now available in bright, primary colors, in addition to the standard black electrician's tape. This pattern on the wall is very MOD looking. (Edit: the pattern above is based on the works by artist Piet Mondrian, which did inspire designer Yves St. Laurent's MOD fashion of the 60s which was partly made famous by the super model, Twiggy.) Whew....I hope I got that right. Thanks Firefly. LOL
Here's a softer version using the same medium.....vinyl electrical tape. You could apply this directly on walls or doors or on a canvas mounted on the wall. Lots of possibilities. Here's the original post by lilybee on Instructables showing step by step. Cool, huh?
P.S. Someone mentioned in the how-to that you need to use the original tape as it adheres well to surfaces. Apparently they tried a cheaper discount store variety with less than favorable results. Vinyl electrical tape is very affordable and can be purchased from any hardware or home improvement store.
