Have you ever been trying to draw something like a mandala, using a plastic protractor, and your tool slides as your drawing? It’s happend to me a lot over the years. It can be frustrating, and makes it difficult to construct something precise!
Well, recently I was shopping in Plunkett’s Stationery in Tucson, Arizona, and I came across these stickers! Since then, I’ve also discovered that you can get them on Amazon.
