Place them right sides together and sew around three sides, leaving one short end open. Keep the fabrics in place with paper clips as you sew.
Turn the rectangle right-side-out, and then fold the short edges in about 1/2? and topstitch to close the remaining short end.
Finger press around the perimeter of the rectangle. Cut a piece of Velcro that’s about 6? long, and sew the “hook” side to the top edge of your rectangle and the “loop” side to the opposite end of the rectangle.
Fold the bottom edge up, so that the bottom Velcro is facing outward and its edge is about 2 1/2? inches from the top edge and then topstitch around three sides of the snack bag, securing the sides and finishing the flap.
