What most cats are likely thinking most of the time.
Painted on 11"x14" watercolour paper. Since these paintings are loose and scrappy, they may have a smudge or two, but that's a big part of their charm.
Signed on the back. Add a note if you want it signed on the front as well.
You don't need to frame it, but here are some tips if you want to.
11"x14" is a very common frame size. You can find it online, and most home decor shops will have it. However, alas, IKEA does not carry 11x14.
You can also take it to your local frame shop and get it custom framed.
