Thrift store paintings are pretty predictable — religious icons, weird clowns, and lots of very boring landscapes. Not many of us would think to include them in our home decor, unless we found a particularly rare gem or were going for a kitschy tongue-in-cheek theme. But we feature projects of upcycled and hacked thrift store finds all the time. Why not embellish a painting? And if you are going to go through the effort, you might as well make it worthwhile, and not bother adding a tree or quaint woodland cottage. Add a monster. A big one.
