This is the simplest afghan there is to make! I bought a variegated yarn where the color is varied in large chunks to create this striped effect. There is no pattern for the afghan - the whole thing is made with double crochet stitches.
For the Scallop Edging~
To Begin: Join yarn or thread in the edge stitch of the piece to which you are adding this edging.
Row 1: Ch 1, sc in first st, * ch 5, skip 4 sts, sc in next st **, repeat from * to ** as many times as needed to complete a row or round.
