I've never used vinegar to make felt but usually some form of soap, but I suspect in doing so it would act as a degreasent as it makes quite a good cleaning agent and may cause the fibres to bond more closely together making a tougher and stiffer piece of felt, I think it may well be an interesting project...

"And the four bare walls stand on the seashore. a wreck a skeleton a monument of that instability and vicissitude to which all things human are subject. Not a dwelling within sight, and the farm labourer, and curious traveller, are the only persons that ever visit the scene where once so many thousands were congregated." T.Lewin 1867
