First take one of the three squares and fold it in half. Stitch along the fold about 1/4 inch from the edge. Place this piece on the right side of one of the remaining fabrics aligning the bottom edges to make a pocket.
Next take the last square of fabric and place it on top of the other two with right sides together. Stitch a 1/2 inch seam along all edges leaving about 1/2 inch open for turning. Trim edges and clip corners. Turn right-side out. (this was the hardest part) Press with an iron. Slip stitch opening or top stitch along the entire outer edge.
Add a closure such as a snap, Velcro or a button if desired.
