I like this thread (pun intended). I like to use my sewing machines a lot. Here is one of my favorites that I think you folks may enjoy. It's called simply Elna, some folks call it a No1 because it was the first sewing machine Elna produced, or the Grasshopper because of its looks. They were made in Switzerland between 1940 and 1952 or so. It is super portable and folds up neatly into this little case.
Here's what it looks like inside:
Here's the Grasshopper all set up. Notice the case makes its own work table, cool design.
Here's a closeup of the Grasshopper for your edification:
I have a couple of these because spare parts are tough to come by. Hope you enjoyed.
