Since having exposed wires is not okay, I decided to do it the old school way and put electrical tape on it. I wasn't too excited about the look. I mean, what did I expect, right?!?
I had just finished crocheting a newborn hat and thought I'll just crochet over the wire using the same pink yarn. My husband saw me and disapproved of my wire wrapping skills and used shrink wrap instead (because it looks cleaner).
I ended up using a smaller hook than pictured. And twisting the wire as I crocheted made it look better. It was fairly simple and quick. Now I have a new (ish) pink charger!
