That leaves top straps that are 12 - 17» (depending on the width
of your
fabric — it will probably be either 44» or 54» to start,
folded in half to 22 - 27») by whatever your
fabric's length is (somewhere between 72 - 90» — longer if you're zaftig, shorter if you're petite; I think 2
yards is probably the minimum), and waist straps that are 10» by the remainder
of the
fabric (between 28» and 46», depending on the length
of the
fabric).
