Things you need for this DIY:
✝ a friendship bracelet
✝ curb chain
✝ an embroidery needle
✝ embroidery thread
<$5 if you make the friendship bracelet yourself
$80 for this Dannijo bracelet? Puh-shaw!
I used a friendship bracelet I made this summer which is why it doesn't have the same pattern although the color scheme is pretty close. You can find a tutorial for the Dannijo pattern here.
First I sewed the curb chain onto the bracelet in one direction...
...then back in the other direction.
And done. Barely broke a sweat.
