I just bought a Singer Pixie (as close as I'm going to get to a Sew Mini as I'm in Canada) and am trying to use it enough to make sure it's not as bad as some reviews I've read.
I used some older Basic Grey paper for this card. It's a larger 6.5X5" size. Thankfully, WS stamps are usually a bit larger and they take care of all that scary empty space!
