Thanks Bob,
A good idea, it never crossed my mind.
I seem to remember a man using one in the market. He was using it on the jeans he had hanging up.
He had a clothes shop, first left as you enter from Wilkinsons side.
He has been left a long time. There is a tobacconist there now.

I had been looking on a web site for one but there were so many conflicting reports I thought I would make a few enquiries before I splashed out and bought one.
