Step 1: Making Hot Chocolate Cone Bags
Preheat your clothes iron to the wool setting...no steam. Place the baggie on the ironing board (covered with heavy paper), lay a cloth over the baggie at an angle and using the edge of your iron, slowly press down along the cloth edge (I count slowly to 7).
Slowly peel back the cloth. Repeat on the other side.
Open the bag to test the seal. It may take a couple tries to get it right depending upon your iron and how long you press it. I messed up several bags before I got it right. Also, don't worry if your bags don't come to a point. It won't matter, especially if you make paper holders for them.
Cut off the excess bag.
