Bet you can't guess what our block is this week! :)
Step 1 - Square-in-a-square
Step 2 - Square-in-a-square
Step 3 - 1/2 square triangles
Step 4 - Flying Geese
Once you've made the above elements, you'll get the blocks in the picture below.
Then you've got a 9-patch to assemble. Once you've done that, you'll have the finished block!
