I haul the machines that are already bruised and battered. Rust and dirt have been removed. They have been cleaned of lint and oiled I have a bit of time in them.... They will hand crank and let kidos punch paper. They honestly can't hurt them. I put them in plastic cases to haul. They will set on the table in wooden boxes. They will go back into plastic cases for over night inside the tent. These are not your work of art machines. Just old junky old re-rehabilitated derelict machines - much better to use them for this than for parts or scrap. Most people want something a lot prettier if they are going to buy one. I'm also going armed with needles, thread and fabric so they can see why sewing machines were invented. If we decide to sew with thread we can - I highly doubt if anybody will stick around real long.
