Minimal 'research', and embarassingly poor quality sewing, but it's done. I wasn't too worried about it, since I was half-way expecting this to be v1, but it gives such a good shape, I don't feel the need to make another.....at least until I get too embarassed of the poor sewing. ;)
Here's what I did:
I started with a big "U", and sewed four 'pockets', and stuffed each with a pillaged pillow -
After messing around with it for a while, I decided it needed a curve, so I chopped off the top and hemmed the opening -
Getting closer! I decided it needed a bit more of a dramatic curve around the waist, so I decided I'd do some pleats across the top -
I have achieved bum!
