The light switch cover is what started the whole idea for the Lego room. I came across one on Pinterest that someone was selling on Etsy. Selling for $50+ ! I figured I could do it myself for way less. I know that Lego is expensive, but we have a tonne of extra pieces, including about 10 Harry Potters.
So I broke out the glue gun and got to work. And I'm very pleased with the result!
