I'm very lucky to have a guy in my life who not only patiently admires every craft project I shove in his face, but also genuinely thinks what I do is cool. He even requests his own projects! To reciprocate that loving support, I've made B several things that your special dude (be it bf, fiance, second cousin, or platonic friend) or yourself might appreciate too this V-Day. Links to original tutorials are below.
Hex nut and leather bracelet: honestly, you know that's Honestly WTF.
Braided leather bracelet: tutorial from I Still Love You. (This is both of our favorite!)
Chain and leather bracelet: my made up version, but very similar idea here.
Note: He doesn't normally wear them all like this, but why should only girls get invitations to arm parties? He said it looked like he was headed to a Justin Bieber concert. What a sport.
