Of course, here are a couple suggestions! :)
Paracord bracelet a lot of army guys wear these.
Paracord Lanyard if your guy isn’t into wearing things around his wrist.
This would be cute tucked into a card.
This is a cute little diy key chain.
There are a couple of ideas. If you need anymore feel free to ask and I will see if I can find some other ideas. Good luck. Submit something if you make something, I LOVE to see others crafts/diys.
