Place the bottle holder on the side of the lining and sew.
Place the right sides together of the outer and lining and sew the top and bottom with an allowance of about 3/8″. Flip the layers so the outer bag pieces are right sides together, and the lining pieces are right sides together. Leave a 1⅝″ on each side of the upper outer layer and a window opening on the lining.
Combine the seams so that a flat base is formed. Sew with an allowance of about 3/8″.

Start inserting the string through one end of the casing, using a safety pin. Continue inserting the string into the casing on the other side. Next, take the other string and start inserting it through the casing from the opposite side. Continue as before. Tie the ends of the string in a knot and pull the ends to close the bag.

YOU ARE FINISHED!
