From the pattern description: Here’s Amy Higgins wearing a cardigan made entirely from gauge swatches. It’s a lounging around at home garment, but full of glamour for when unexpected guests arrive. This cardigan is made up of thirty rectangles and four buttons. It’s simple to make, easy to wear, and the design is adaptable. We knitted it (mostly) in seed stitch and brick stitches, but the squares can all be different stitches and colors.
