So... if you want in head on over to the Marshamallow Surprise! Facebook page, like or comment the official giveaway post to enter, then be patient — the drawing is being held next Thursday (March 27). The deadline to enter is Wednesday, March 26!
What do you win?! A set of three 2" magnet paintings! With original art! Here's a sketch of what they'll look like and the basic run-down (I have to buy the canvas for them, I ran out).
Also, here's a link to the official rules and T's & C's.
