I wasn't planning on making personalized hangers - I was going to get simple wooden ones and add a ribbon bow. But when I saw these hangers in Walmart, I figured I can kill two birds with one stone. There was a 3-pack hangers with the wire across with the clips (like the groom's hanger on the picture). I got my FI to take away the wire from 2 hangers and kept the 3rd one as is for his pants. Next step - some wiring. And then I put the wires in the hanger's existing holes with some hot glue. It took me literally an hour to make all 3 hangers. There is still a bow to add.
Tip: use the paper template to align your letters against. So much easier that way to keep it straight.
