Here is my first crafting tutorial!
I made these canvases a few months ago and they were pretty easy and inexpensive. Just make sure you have some time allocated to wait for each layer of paint to dry.
I used 3- 9″x9″ square canvases and some acrylic paint. It was as easy as taping off a section and painting, the one trick I used was to ModPodge the edges of the tape and allow that to dry before painting that way the tape was sealed to the canvas and the lines were crisp.
