Download the bonnet template and use as a guide on a piece of heavy-stock paper.
Use hole punch to make a hole on each side, 1/2 inch beneath fold line and 1/2 inch from edge. Mark spots 5 1/2 inches from each bottom edge, then make a 3-inch vertical cut line from each point.
Fold across dotted line to make cuff; thread ribbon through each hole. Fold bottom corners inward to create back of bonnet, above, and secure with glue dots; fold down back flap and secure with glue dots.
