This pouch is perfect for classroom treats or handing out candy for Halloween! The pouch is approximately 5-1/2" x 4-1/2" when assembled and holds treats up to 1/2" in width, such as chocolate or gum (as pictured). The pouch is one piece and is compatible with both the 8x12 and 12x12 mats. Simply fold in half, placing small bits of adhesive on the curves of the pouch, then fold the bat flap down. Adhere the center of the bat on the pouch, lifting the wings up slightly. Fill as desired! You can see more here: http://jamielanedesigns.blogspot.com/2016/08/artisan-pouches.html
