Wrapping a mandrel, then getting the fabric tube onto the inner tube is not so easy.
Gave up and was washing up, paper towel holder was empty. Bingo.
Wrap the fabric around the tube, slide the tube onto the inner tube at the joints, remove if possible, but why worry if not. It can get gone later on.
