They're 6 1/2"
But you could make them any size you want
I didn't buy much of the fabric so I had to think what I could do.
For the 9 patch...
I started with 8" blocks
Put both the white and blue right side UP
Sliced 2 vertical and horizontal swipes
Switched up the colors to make the 9 patch
Sewed (make sure to keep them in order)
Then trimmed
The snow flake I had done in a swap over at the Block Lotto
Here's a link to the pattern and lotto
