I made my pattern for the pockets by tracing the outline of the hip belt and adding a little more space at the tapered end to fit two Clif bars comfortably. Then I added a 1/2 inch seam allowance to the paper pattern. I then just sewed them into pouches. Then I sewed the pouches onto the hip belt. Make sure that when you are sewing the pouches onto the belt that you don't stretch the pouches out, otherwise, when the belt is stretched on your hips, you are compromising the pouch's size capacity and it will be uncomfortable on your hip (when you have things in them).
