First, I bought a cheap white 10x10 canvas from Big Lots for $5. Then I spray painted it with glossy Krylon spray paint in Navy. Since my canvas was white, I had to paint a few coats. Be patient & let it dry in between coats or you'll end up with a streaky mess!
After I sprayed my canvas, I grabbed an array of white paints, a pencil, fine tipped paint brushes, & printed a big ol' ampersand out on my computer. I found the ampersand I liked on Pinterest and I used photoshop to make it big - really big- like 7" or so.
After I outlined my stencil, I started painting! I used a color called egg shell for the overall color, and then on the left edges of my ampersand, I painted bright white to give a little dimension (although it's hard to tell from the picture). Make sure you use a fine tip paint brush that's not too flimsy. My tip was probably about 1/4" thick with a pointed tip.
