Hello! This is my first instructable. It's not really something complicated that requires step-by-step directions, but I still wanted to share the idea. Enjoy !
Step 1: Materials
You will need...
A simple image you like
Self adhesive magnets (I purchased leftovers from a print shop, but they are also available in arts and crafts stores)
Depending on the size of your canvas, you should use a different size of image. For exemple, if your canvas is very big, a complex image will turn out huge. I had good results with nintendo sprites on big canvas.
