There were a couple of 20" by 16" ones that were calling for immediate action. This morning they received two coats of black paint. (I used a semi-gloss interior latex because that's what I had on hand and I figured it would be more durable than my Apple Barrel craft paint from Walmart. When Light Sabor duals are a daily event in one's house, durability is an absolute must!
Then I whipped out a couple of Alphabet decals using my vinyl cutter and rubbed them on.
They went from blank canvases to hanging on the wall in just a few hours. Easy peasy.
