Let’s face it, they don’t go back into the box they came out of.
They will tangle together no matter what you try to do to prevent it.
The bulbs break and Heaven forbid you have the kind of lights that are wired in series (the older kinds) that if one light goes out, they all go out.
Each set of lights needs its own, soft, bag for 11 month storage.
So I made some out of old baby clothes of my kids! Baby summer dresses are perfect because the sleeves/handles are already hemmed.I decided the sew under the top ruffle because the bottom ruffle was just too much extra fabric. Once sewn, I cut the bottom ruffle off. I got a lot of Christmas lights so I’ll be making a lot of bags for them as I take them down one by one and store them in a dorm room, zip up laundry tote.
