American Flag Blanket
This pattern generally consists of two parts: the Ribbed Brim (the bottom band) and the Body (the part with the 3D leaves). The stitch used for the body is a repeating sequence of a base stitch and the Leaf Stitch (often a specific arrangement of Double Crochet or Puff/Bobble Stitches).
The brim is worked in a flat strip and then seamed to form a circle.
The body is worked in the round, often using SC BLO or Half Double Crochet (HDC) as the base stitch to maintain a dense, knit-like look.
