Hahahaha!!!! sooooo funny! Buy white mugs and paint funny things on them! (Pigs nose, Moustaches, etc...) This would make GREAT Christmas gifts too, with some cocoas or teas! I might do this for someone..
Easy abstract painting that anyone can do! Just blob the paint on the canvas in random spots and blend! (would be interesting how students could make different pictures w/ the same colors and same blob positions)
Another DIY wine cork project (link doesn't show you how to do it, but you cut your corks in half, hot glue them together in a honeycomb shape, then hot glue a strip of fabric or burlap around the shape to secure)
These hand-painted 5"x7" canvases are the perfect decoration for Fall, and can be used as a decoration inside, as well as outside. They re painted with acrylic paints, and then finished with Mod Podge to give them a shiny look.
