Start with a pair of scissors, a set of those circle stickers/seals (you can find anywhere - office supply/grocery/Target) and a white canvas.
Cut the circles in half.
Start attaching the half moons to your canvas end to end.
Go over the whole thing with a little white school glue - to keep those pesky edges from curling up. Then flip it upside or keep it the way I have it above. Hang!
Fun little project to add some brightness wherever it's needed!
