I sent Diane Claus a classic black on white tile and she gave it some wonderful additions.
I sent an ATC with a strip of holographic paper through the middle to Sandy Kelly-Jones. She continued the black-and-white theme on the other half.
I sent a colored ATC to Debra Huff and she completed it with two of my tangles (!), Skye and Copada.
I sent similar tiles to four people for a "Summer" theme swap.
Kim Aarts-Bruin in the Netherlands added to it, minimally and beautifully, with some Ruutz and little flourishes.
Prairie Kittin in the US borrowed a purple pen from a friend to complete this tile! So nicely done.
