This one's a mystery. It came with some old blankets needed for packing furniture in a van.
It seems to be hand-made, then folded in half and sewn up on two sides to make a sleeping bag.
But it's too small for a human adult - although a child would fit - I thought maybe it's for putting a dog in after a bath?
It's about 1m long. Shoe for scale.
Collect from Yatton Keynell.
Any use to anyone (or their dog)?
