I make them out of hemp if anyone is interested in non-beaded ones. I can make them in a range of colors, sizes, embellishments, and styles. Check out my shop for a few examples. www.spingypsyshoppe.etsy.com
I love them & they are really easy to make. I used to make them with stretch cord but now I make it more fitted like an anklet.
I make hemp barefoot sandals. My ETSY store goes online in May, but you can check out some of my work on Facebook. http://www.facebook.com/tangledmacrame
