Crochet "Cord Tamer" ~ This is a great idea! I use bread "twistie ties", but Son-in-Law worries they might be too tight & may harm my gadget (camera, kindle, etc. These would hold them fast, & I'm sure would never damage them.
Love the little charm tassels on the ends. Looks like a shell-type stitch with picots on top, and also worked on the other side of the foundation row. --Pia (A ton of crocheted bookmarks for craft fairs, etc.
