I've only treadled a few test stitches so far. It IS fun and surprisingly easy to run the machine. Easy enough that I can see why it took so long for electric machines to dominate the market. I'm still learning starting and stopping.
Sorry for the hijack. Back to featherweights. You can buy a bunch of treadle machines for the cost of 1 featherweight. They're harder to carry around though.
