The corners of the flap (far left end) are rounded using the corner rounder. Finally the seam is prepared for adhesion. In this example, double-stick tape is used. PVA or PVA mixture can also be used, but the tape eliminates the consideration of drying time. Finally, the front panel is cut at an angle as shown. This cut allows easier access to the material contained in the enclosure. Measurement A should not exceed Measurement B, or the flap will not cover the angled opening in the inner enclosure's front.
