I could have a go if I had any knitting needles....it would be a basic tube cinched in at the top with stragetic holes for the spout and handle. Will that do?
I hated it fried, it went this weird dark pink I remember spam and lettuce sarnies.
I preferred cheese and pickle as a kid. You only got ham on special occasions....the only other sarny filling was egg, not with mayo either, sliced hard boiled!
