Christmas Light Storage for Sewers

I am always emptying bolts of fabric which leave these cardboard "boards" as they are often called by fabric enthusiasts. We took down the Christmas tree and were packing up the lights, oranaments, etc. I had a few emptied boards and my husband smartly wrapped up lights on them, each held 3 sets of 100 lights and tucked perfectly into the storage bins. I thought this was a great use of these sturdy boards which often end up in the recycling bin.
