This is a great way to use up odds and ends of yarn from other projects, while trying out different granny square patterns. To pull it together, I connected all the squares with white yarn and single crochet. This picture was taken before adding about a 2 inch wide ruffly border - comprised of a few single crochet rows and ruffles made by chaining 5, then slip stitch to the single crochet, repeat. Easy and pretty!
The bottom picture shows another scrap-ghan, complete with ruffly border. I love incorporating 3-dimensional squares like the flowers, and textural elements like popcorn stitch.
Both of these blankets were donated to children in poverty here in Toledo, via Love Squared.
