Gather your supplies
Protect your area from the paint and begin painting the whole canvas with the color you want as the design. (Forgot to take pic, sorry I'm human...)
Lay your 1in painters tape on the paper cutter so there is a 1/2in on either side of the cutting part
Cut tape and remove carefully from the paper cutter
Lay the tape any direction that you choose on the canvas
Make sure tape is firmly on canvas and begin to paint your second color
After it dries, remove tape carefully and make any necessary touch ups.
Yay now it looks cool!
Hang it up and now you have some art on that previously blank and boring wall!
