and here, without further ado, is how to make this variation, using ONE SEAM:
you
need four pieces: a circle for the skirt, two straps, and one piece
for a "waist" band. to decide how wide to make your straps, measure
from the center of your bust to just under your arm. to figure the
length i just decided on 1.5 times my height, which i rounded to 90"
because that was easier to figure out than 64.75 X 1.5. the skirt
length is your choice. the band needs to be a little longer than your
waist measurement--i didn't measure the length of my band, i just sewed
it on and cut it off when i had gone all the way around the waist.
the next part sounds complicated but it is not. turn your
skirt inside out--you are going to sew from the INSIDE of the
waist--which means you don't need a free arm on your machine. overlap
the straps 3"-4"...
this is the one and only seam.
when the dress is done, it will look like this (that's a 60" measuring tape on the strap):
