I have an original WW2 leather rifle sling that is stiff with age. I would like to soften/re-condition it sufficiently to use. What is the best, and idiot proof way of doing this, please?
I have never worked in leather, so am a complete virgin, and would also like to know availability of products in the UK, that may help. Application of the KISS Principle then, would be most appreciated!
Thanks in anticipation.
