1. Follow the fabric purse organizer tutorial to create this organizer. The tutorial shows a zipper being used. Instead of using a zipper, you can also use velcro.
2. Iron a 1 cm seam allowance on the top open edge. Cut the two velcro sides the same width as the opening and sew these to the top of each side, covering and adhering the seam allowance at the same time.
You can also choose to follow the tutorial for the zipper and insert a zipper as instructed.
