I'm up to June 10th. This block is called 12 Crowns. Each "crown" has 11 pieces, plus there are four corner blocks. That adds up to 136 pieces - in a 6" block! (only 12 flying geese though)
One fun part about this, often the blocks start out easy and then using the same techniques, get more complicated, so by the time you get to one like this, you've had quite a bit of practice doing the methods on a larger scale.
