definitly 2 different products. wax paper is see through with a wax coating ... when i was a kid we used to collect leaves and press them between 2 pieces of wax paper.
freezer paper is white. paper on one side a plastic coating on the other. also known as butcher paper, it is used with the plastic side to the inside to wrap meat at butcher shops. you can usually see through it pretty easy so it's good for tracing applique shapes. the plastic coating DOES NOT COME OFF ON YOUR FABRIC you can iron the coated side to your fabrics and cut on the lines. the freezer paper can be removed and reused many times and is a staple in alot of quilting/sewing rooms. wax paper..not so much....
