I am on the Hero Arts Flickr group, and a lady there, Deborah Nolan, runs a really neat swap called Card Chain Challenge, or CCC for short. Each month (as far as I can tell), you have three choices to do a card with: a colour palette, a sketch, or a theme.. now if you want to, you can do more than one choice, such as a themed card in the colour palette. You only send out one card a month, but, be warned, this is an international swap. This is the first month that I've joined, so it'll be interesting to see what I get. I am putting my card in the mail Monday, so until the lady who is the recipient tells me she has the card, you'll be left in suspense to what I've done.
Deborah's blog is HERE, so if you're interested in checking out this swap
