Cluster granny blanket square, you will love this beautiful little square, makes a warm blanket when assembled. I love the how the holes in the corners of the granny square leave a diamond pattern running through it.
Each square measures 4.5 inches by 4.5 inches so you can make blankets any size you want from baby to afghan or throws, I have used a simple double crochet together (treble for UK) stitch to make the clusters with a single crochet edge.
