What a lovely idea GI Jane. I would perhaps make sure Teddy is not hear a radiator and preferably stored somewhere cool. You could perhaps get away with spraying a light mist of oil on him or rubbing some into his seams. Something like a sweet almond oil or a dry oil of some kind. Obviously you don't want to get him greasy, but a light mist might work. I'd give it a go anyway. I will ask for you, as i work next to a teddy bear shop and she sells all manner of vintage and new bears.
