This idea was introduced on Alteredartswap group on yahoo. Each player (group limit of 13 - you receive 12 pieces back) makes a 3x3 piece based on each player's themes/choices. Mail it to them directly and they assemble them into a 9 x 12 canvas. I've only seen one finished so far and am waiting on mine to finish one, but it has been SO fun. A challenge to work in many themes and with colors that may not be your first choice. Can you say s-t-r-e-t-c-h?
