Use a wire and a wooden block. Tricky part would be getting the design perfectly flat and just how you want it.
I’d suggest writing your word out on paper just how you want it. Bend the wire over it to match, making sure you leave a long tail to attach it to the wood. Drill small hols in the wood to accept the wire, and glue finished wire in place. Heat up and stamp onto project as shown. Love this idea from TheDressIMade.
