My sister, currently an EMT, is working on becoming a full Paramedic. A few years ago, she asked about patches for her ambulance district. It’s a common tradition amongst emergency services (police, fire, EMS) to trade patches with other departments. Since her district didn’t really have a custom patch, she wondered if I could work up some designs to present to her boss. While the patches haven’t progressed, I did work up several variations.
These are the ones I most liked out of the 4 or so main variations.
