You should also choose interfacing based on weight--how stiff and thick you want your interfaced piece to be. To make a collar stand up or a tote bag sit upright on a table you want a heavier interfacing. For lightweight fabric and light tailoring you will want a lighter interfacing. Remember that, when buying interfacing in the store, it will be heavier once the glue is bonded to the fabric. So if in doubt, go with the lighter one.
