We've had a few variations of this swap, so I am labeling by month and year instead of number. Hooray.

Very easy peasy. Send each of your partners 2 ATC's that you have made.
Any theme, any style, any media. Make them for this swap or just use ones you have left over or never quite get around to sending. You decide.

They do have to be made by you though for this specific swap.

You will be sending out a total of 6 ATC's. 2 to each 3 partners.

Very good.

Edit

since we did not get enough people to do the swap as originally intended, we will be sending 3 atcs each to our 2 partners.
