Last week I redid a couple of blocks that I was unhappy with for my Farmer's Wife quilt.
First up was Block 29, Economy. I was really unhappy with how my first one turned out; it had way too much white and was really boring. I swapped the two colors per Amanda's suggestion, and the result was absolutely perfect. So much better!
I also redid Block 18, Century of Progress. I didn't like how the book laid it out to be non-symmetric, but now it is. Woohoo!
