Piece of fabric 18″ x 42″  (45cm x 107cm) or 2 pieces 18″ x 22″  ( 45cm x 56cm) sewn together.

70″ ( 180 cm) ribbon/tape/cord for drawstring, cut into two equals lengths.

Instructions

Fold the fabric right sides together to make a rectangle 18″ x 21″ and press

At the top 3″ (8cm) fold back the seam allowance 1/4″ (6mm) and then 1/4″ (6mm) again and stitch.  This give a neat edge to the opening for the drawstring.

Fold down 1″ (2.5cm) front and back to form the channel for the drawstring and stitch close to the edge making sure the raw edge stays folded away underneath.

Thread two lengths of ribbon /tape/cord through the channels and knot or sew two lops.
