I recently participated in a Sudoku swap over on CCSwaps. For those of you who are unfamiliar with a Sudoku swap, it is a collaborative swap. Each person makes 4 backgrounds which are then passed on to the next person in line. Essentially, every person in the swap does a different stage on each of the other players cards. At the end of the swp each person received 4 finished ATCs. It's a lot of fun.
Our group was named the yellow group; the participants were Chris Bennett, Jessie Sherf, Sandy Proulx and Adrienne Goodenough . I love the artwork that resulted from this collaboration!
