See detailed via about hinging canvas to the wall to hide unsightly eyesores. I think it’s an excellent idea. Micheal’s always have sales on their canvases and you can use 40% coupons if they’re regular priced. I thought the gallery wall below is fitting for this post because it’s an entry way area which is usually where the eyesores are located…
If you have shoe boxes lying around, maybe use the lids as a “canvas” and paint them and arrange in a way to cover whatever needs covering.
