You will need:
2 (12- by 24-inch) pieces of cotton flannel
1 (12- by 24-inch) piece of cotton batting
Straight pins Embroidery thread and needle
1. Stack the flannel pieces with right sides together (see tip below), then add the batting to the top of the stack. Pin the stack together along the edges.
2. Sew a running stitch along both long sides and one short side of the stack. Knot the thread and trim any excess.
3. Turn the stack right side out. With the short, unstitched side forming the bag's top edge, fold up the bottom edge three quarters of the way so that it lies 3 inches from the top. Whipstitch along both sides to close the bag.
4. Fold in the raw edges at the top of the back panel and iron the creases. Use a whipstitch to join them. Knot the thread and trim any excess.
