Here's what I have so far for the shape of the bird blocks at the end of day 1. I was playing with this configuration at one point, but gave up because I wasn't quite sure how I would go about finishing the edges since the blocks were offset.
So I squared each block up and started choosing fabrics for the block to go with. After trying several, I ended up deciding on this one. It still looks way too blah to me, so I will probably end up re-shaping the blocks again.
I have a pile of coordinating fabrics still, so I may make the blocks bigger and a little more interesting. I'll sleep on it tonight and maybe I'll get an idea sometime during the day tomorrow.
