I've been redoing my room....and this means changing out things like my old cord covers. I was really tired of sewing, and so I decided to do a 'fake' seam with my glue gun. I cut a piece of burlap two times the length of the cord I wanted to cover.
I just glued down the sides.
Until I had a long tube.
Then I squished it down he cord I wanted to cover. You can buy flame resistant fabric spray, but I never light these candles, so I'm pretty safe.
