DIY: lace tape t-shirt...So cool looking. You could easily recreate this with some lace and a dark colored T-shirt which can be bought at your favorite obliging thrift store.
Canvas, Masking Tape, Spray Paint - So easy! - When I pulled off the tape, it looked a little "messy." Some of the spray paint had found its way under the tape. I ended up touching it up with white paint to perfect the lines. It's a great piece of artwork though and it gets tons of compliments.
DIY: ombre t-shirt (make your own). Might also be cool to try taping or covering a section of the shirt in a pattern/design and then removing the tape after spraying so that you get a really cool imprint on the shirt. Dont know if it will work or not though... just a thought
