I've always loved Schoolhouse Electric's cloth cord styles and thought I could do something similar here with just a dab of glue and a bit of colorful yarn.
You only need glue when you're starting and ending, and the tighter you wrap the yarn, the better! I found it was helpful to wrap the yarn around a glue stick or a popsicle stick before wrapping the cord. It helps keep everything tight and untangled. Also, just to be safe, I didn't wrap the cords all the way down to the plug (I left a good two feet unwrapped).
I love when simple projects make inexpensive finds look extra special! The project cost me nothing and I was happy to give new life to these sconces we've been storing for years! :)
