I finished my homework for class #2 today - 10 blocks. I'm up to 224 pieces. I learned that with a lot of small pieces, and therefore many seams, I need to make my seam allowance smaller to allow for the height of the seams (if that makes sense) so that my finished square isn't too small. K4 is a bit small and I think that might be why. And my fabric colour is a lot brighter in person - maybe too much light?
