Catheter Bag Covers Instructions
Cut fabric 11" x 26". Fold in half, right sides together, so that it now measures 11" x 13". Sew the two sides together.
If using fabric for ties, cut them 2" wide by about 21" long. Turn in raw edges and sew down the long side. Fold these in half and place on each side of the bag. Sew a narrow hem in the top of the bag, including the ties on each side over the seam.
Bag should end up being about 10" x 12" with two ties about 10” long on each top side.
There are probably many ways this size can be accomplished and any of them are fine. Coordinating grosgrain ribbon can be used for the ties, as well as any bias binding you might have from a previous project.
