I was wondering if anyone has ever thought about this before......

When I received my hanging strop, they said that the linen side was
"pre-treated" with a chalk.

Indeed, when I first put the strop into use, a very small amount of white
substance was noticable on the linen side !

*QUESTION*.... Chalk ?......If I buy a box of blackboard chalk (the kind
school children use), and treat my linen with.....

Is that good or bad ?

Thanks.....Marko.
