We started doing leatherwork because we wanted to make our own shoes.
We started to fumble with leather to see how far we would get and make our own shoes in the end. Every now and then we sell something at markets, in order not to pile up the results of experimentation in the house and be able to buy leather and other materials for the next project. Museums like Haithabu used to have a nice exposition of tools and reconstructed replica's of interesting shoe finds. In 2010 the exposition was renovated and de shoes have, sadly enough, mostly disappeared from the eye of the public.
Mostly we tend to go to events to demonstrate to the public how the work of leatherworking was done with tools as authentically reconstructed as we can get hold of.
