I felt like painting the other day, and so I decided to decorate a blank pencil bag (or you could use it for whatever) that I bought at Hobby Lobby awhile back. I did one once before freehanded (it was an MGMT one!), but I wanted to try out painter's tape this time. I made some triangles and rectangles with the painter's tape first, and then pretty much just swirled random colours around. Then I removed the tape and wala! The paint went under the tape in a couple of places, but I really like the outcome anyway!
