I've only made 3 so far, but am seriously tempted to make a couple more of these tree blocks.
This is one of the swap blocks we can make for the guild bus trip coming up in 3 weeks. Because the shop hop bus trip is going to the beautiful Black Hills, participants can make these tree blocks and enter them in a drawing to win several of them.
We can also choose to do a star block, and so far I've only made one of those. But I think more are in my future. More blocks entered means more chances to win.
