I love Honestly WTF for their amazing DIY posts, and I actually found this whilst browsing Pinterest [now there's a surprise...anyone else as addicted as I am?]
Check out the tutorial here. All you need is leather cord, linen cord, brass ball/crystal chain, a hex nut and scissors. I didn't have a hex nut, so used some random ring I found for the clasp [not sure what it is, but it does the job!]. It didn't take long at all, or cost much, to make but I reckon it looks quite effective. I also made a single one in purple.
I think they look great worn alone or piled together with other bracelets! Anyone else found some great DIYs on Honestly WTF?
