CONSTRUCTING the Cover Flap:
On the cover with the open end, turn down the two sides that are 3.5” to a ¼” and then another ¼”. Topstitch this.
Put one piece of loop Velcro on the inside just below this topstitching. Do this for both sides.
With the two small pieces of line that are left, place these right side up and secure the Velcro hooks to the edge of each piece. The adhesive will prevent any fraying so no further stitching is necessary.
Place one of the Velcro strips right side down onto one of the two remaining triangles. Place the other strip on the other side. Stitch in place.
With right sides together, stitch the two triangles together on the two Velcro sides, leaving the 5” side open.
Trim corner and turn right side out.
Trim the end pieces.
With right sides together, sew the flap to the 5 “ side of the open triangle cover. Zig zag the edge.
As an alternative, stitch only one part of the flap and fold the other in and topstitch.
Turn right side out.
