Drawing in a Walsall saddlery

I've been drawing in a Walsall saddlery to produce work for an 'Echoes' project run by Walsall Leather Museum.  It was a fascinating time gaining a glimpse into this small business.  The building was used as a leather horse collar workshop in the early 1800s but with the growth of other means of transport, this died out and it's fitting that a leather business continues to be in the same premises.
I'm wondering whether to create an etching or drypoint from my sketches.
