Returning home I remembered a friend had an upcoming birthday and set about making her a present. Not having measurements, I was lucky - the fabric was stretchy, so I was able to use my judgement and exact proportions weren't required.
It made up beautifully and just to add a little touch to the pink I embellished the back with an organza bow.
Happily, the gift fitted just right.
Now - think I have enough left for something for myself!
