These two squares are from 200 Crochet Blocks for Blankets, Throws, and Afghans: Crochet Squares to Mix and Match (I’m using the 2005 edition with the red color scheme on the color).
Tricolour Square (#35 – 200 Crochet Blocks)
Granny in the Middle (#117 – 200 Crochet Blocks)
I really wanted to experiment with color combos on this one, so I spent a couple days stitching these up.
