I have always wondered why somebody couldn't come up with a continuous-feed bobbin for sewing machines, so you wouldn't have to keep stopping to re-fill bobbins.
NOW, I have another "gee I wish somebody would....." wish: an automatic warp-maker. You know, you could just thread your warp yarns up, punch in the settings and walk away while some little electronic elf made your warp for you! A buzzer would sound, once you've had you nice cup of tea, and you go and grab your perfectly-tensioned warp and get to dressing your loom(-;
This is the only part of dressing my loom I really hate, whether winding it on a board or reel, or sectional-beaming. I actually enjoy threading and beaming, etc, but just making the damned warps is enough to drive me to drink.
ending whine du jour,
