So, my project is officially a work in progress.

I bought a sewing machine from a junky today.
He found it in a canal, so it's sustainable.
Only, the junky was disguised as a sweet old man who owns a little shop in Weesp that specializes in selling sewing machines (as well as thread and zippers).

It is a 1969 PMC Lichtgewicht (a child of the 60s, probably a rebel in its time. and lightweight, about 20 kilo, so very portable, would probably be a good conversation piece while hitch hiking)
