Take 1 x large and 1 x small piece of fabric. The small piece is the one you will see on the outside, and the large piece is the lining that will go onto this smaller piece.
Place VELCRO® brand tape on the RIGHT side of the smaller piece along the 22cm edge, 1.5 cm down from the top and equidistant from the raw side edges.
Pin the VELCRO® brand tape in place by placing pins vertically to the horizontal piece of Velcro.
Sew around the VELCRO® brand tape in a box shape, sewing as close to the edge of the VELCRO® brand tape as you can but making sure you catch it all!
Apply the VELCRO® brand tape in the same way to the large square piece 1.5cm down from the top.
