I have had this DIY tutorial by Honestly...WTF saved for ages and I haven't had the courage to make it till I saw someone wearing a Hex Nut Bracelet at a market the other day. Well its definitely not going to be a new Bow Peep product because it took about four hours to make and its not very neat. Even if I got it looking better I would charge a fortune just because it takes so long to make.
If you want to try making one yourself the instructions can be found here.
This is the Honestly...WTF version

I think after some practice it could be much neater but I don't think I have the time or patience to get it looking as neat as theirs.
Let me know if you try making it!
