This soft cotton flannel is a premium 100% cotton yarn-dyed flannel; that means it's identical on both sides, with the plaid woven into rather than printed onto the fabric. Marcus Fabrics calls this a Lumberjack Plaid. It can be used for pillows, quilts, or clothing, and makes wonderful pyjamas.
This fabric is sold in half yard increments: one unit equals one half yard. The fabric will be cut in one continuous piece regardless of how many units you order (i.e. if you order 4 units you will receive a single 2 yard piece).
