Several times a year the guild does block drawings, block challenges or a block exchange. Below you will find the links to our current and past block challenges and exchanges. What's the difference - a drawing usually is two blocks from a set pattern. One for you to keep, one is donated to the guild for auction. An exchange is a group of blocks that participants make and then swaps with the other participants. Lastly, a challenge can be an entire group project or a series of blocks.
