Block 4

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.

One more square-in-a-square for the centre.

Then you've got a 9-patch to assemble.  Once you've done that, you'll have the finished block!
