When I was kid my mother used to make most of my clothes. As she always bought too much fabric (just to be on the safe side, eh?) she never made just one thing, and I think I've absorbed that habit.
The yellow cushion was made with leftovers and still I managed to eke it out to make a little bag. I bough this 1970s print skirt at the fleamarket and with the fabric I cut off when I shortened it, I was able to make a belt and use a buckle I've been saving for years.
