I searched around for some good sources of designs and found a few that I liked. I then print those out on the colored paper and cut them out along the lines... Not much to it!
The first papercut I did, a fantasy castle. The merlons gave me a bit of trouble -- they're kinda crooked. I stuck it on a page from the 'Once Upon A Time' mat stack from DCWV, and I'm pretty pleased with how it turned out. This became a card I sent to a member of the brievenbus community.
Playful kittens, for gertvr and xaviar_nl, to thank them for the advice on papercutting and their kind words after Grandma passed away. Stuck to a piece of cardstock from a stack that we had lying around.
Mother Goose, for babarage and J., for pretty much the same thing.
There was another design that I did, that got stolen by klik to use in her art journal.
