You made a spiderweb!
When the kids were little, and in the same room my sewing room is now, used to be a dining room, I gave each kid a ball of yarn and told them they could make a spiderweb. Admittedly, on cold snowy days they needed 'something' to do. So they were busy for a couple of hours winding that yarn in the rungs of the chairs and around eveerything in the room. We left it for a couple of days, it was their masterpiece.
Was this your version of a masterpiece?
