The comment about voice-activated machines is kind of funny, but probably actually pretty true! No reason they couldn't make them this way now! "Siri, give me a 3mm zig zag, 50% speed!" LOL
I want a machine that watches my shoulders as I'm quilting, and will slow down the machine as my shoulders creep upwards, stopping if they get too high. THAT might finally break my terrible habit of clenching them all up around my neck as I do my FMQ!
