FCMA: Every Color of Paint

Make a postcard for your partner using every color of paint you have at hand. Just a small dab or dot, smear or splatter. Make the postcard yourself out of card stock or recycled materials, or use a blank postcard (Strathmore makes blank postcard pads.)

One post card to one partner. These swaps are always international - ask me if you want USA-only versions.

From the USPS:

But to qualify for mailing at the First-Class Mail postcard price, it must be:

Rectangular At least 3-1/2 inches high x 5 inches long x 0.007 inch thick No more than 4-1/4 inches high x 6 inches long x 0.016 inches thick
