I just finished up making 25 of these granny squares. I started out making 11 for a cookie exchange with other members of the MMQG, however, I wasn't able to drop them off in time for the exchange. So instead, I just thought I'd make some more for a larger quilt and have them all match.
The fabrics used: Oliver + S - City Weekend, Heather Ross - Mendocino Kelp Forest and Studio e - Fresh Aire. I used a strip piece method to piece the blocks.
Now my 25 blocks are done, time to trim and figure out how I want to sew them together.
