Clever clever DIY: chalkboard paint on party glasses. Much easier than painting and you don't get brush lines. I also like the idea of dipping each one in different colors so no one loses their glass :)
transferring image to wood: cut wax paper to size of printer paper, put through printer with guidance, place ink side down on contrasting wood, push ink into wood using the edge of a card - use muscle, gently lift and seal.
This is insanely clever and I imagine loads of fun! Who does not like popping bubble wrap first off, and then add paint = deal! - Bubble Wrap Stomp Painting - make some bubble wrap "boots" then dip in paint and stomp around to create art!
