I wanted a new casual winter skirt, without spending much money though, so I bought a long flarey cord skirt from the local charity shop (it worked out at less than £1), and chopped the bottom off. (I measured to the same length at several point around the skirt, marked it with pins, and cut round by eye, joining up the pins, then hemmed it.)
With the spare fabric, I made some roses. (Cut long strips, folded them in half, sewed along the bottom in my largest stitch width, then gathered them up, and stitched them into place.)
My new skirt.
