I used this awesome template and some Jenni Bowlin paint to do the masking in the corners. Since this layout is essentially about numbers, I immediately thought about this template. I'm not super happy with how it turned out, but it was fun to do. =) The rest of the supplies came from my Studio Calico kits (I LOVE that I'm being pushed to finally use my kit stuff!). Super fun and relatively quick. =)
Thanks for looking!
