Step 23: Sewing While Filling New Bobbin
Pete Lynne's sewing machine has two feed spools on it. That way when his bobbin runs out of thread, he can take a loaded bobbin off the bobbin winder and put the empty one on it.
Then he KEEPS SEWING!
The bobbin winder spins while the machine sews and automatically shuts off when the bobbin is full.
I've sewed for decades including commercial sewing, and I never learned this trick.
I always loaded bobbins ahead of time, bought pre-loaded bobbins, or stopped and loaded them at the time. All those methods take unnecessary time. I want that time back!
btw that's the best sewing machine any of us have ever used, a "Unicorn" from Korea. It's incredible.
