Keep Calm & Do It Yourself: DIY Balmain Denim Jacket // TUTORIAL - Great tutorial for adding contrasting fabric. The spikes and studs are not my style. Would probably use something else, maybe gems and pearl beads.
Upcycled Jeansjacket - I did this with an old painting. I didn't cut out the jacket though. It would definitely be easer, but the back of the embroidery isn't protected this way either. I would at least line the insert.
