Art on cymbals

My boyfriend is a (hard hitting) drummer, so we’ve got cases full of cracked cymbals lying around. One day I decided to create art on used cymbals. All cymbals I draw on are used and contain cracks. I remove the logo decals from the top side of the cymbal to create more drawing surface. The cymbals are unpolished and may contain some patina. The cymbals I draw on are mostly Zildjian A-Custom’s but I also draw on Wuhan-, Ufip- and Amedia cymbals.
