These little guys are a little tricky to work with, but they're really cute if you've got some patience!
Round filigree hair beads come in packs of 8 and can easily be bent open into quarters (see the third product picture). You can add them onto dreads or braids by opening them up and clamping them back into their original shape, or by sewing them onto the extensions through the holes on each end. For an extra secure hold, clamp them onto the extension first, then secure them with a little bit of thread through the openings.
