Needle and thread
Very easyIn the stitch-it-together-idly-in-front-of-the-TV-and-forget-you're-even-doing-it sense. This one's a quick, straightforward - you could say - mindless act of customising!
TimeAbout half an hour.
Make circles out of each your trims by pinning small darts along the edge of the trim, so that it curves round, until it forms a circle. Cut it., stitch the edges together and stitch the darts in place. Stitch the trims on top of each other, with the widest circle at the bottom, to make a fabric rosette. Repeat this process a second time.
How it's done
Pierce a hole for each brooch on your shoes. Attach the brooch to the rosette and through the hold on the shoe (I put mine on the strap). Repeat the process for a second time. You might also want to ad it out or cover the back of the brooch to stop it from digging in.
