Can you believe they were all created by stencils*? I think these are a great alternative to wall paper (to which my husband strongly objects.. I don't blame him- it's pretty, but a pain to put up/take down) and wall decals. I love that they are reusable. They also seem relatively easy to use and they definitely add beauty to a space.

*Cutting Edge Stencils has no clue who I am and does not pay me to blog about them. I just think their stuff is really cool :)
