I had no idea such a thing existed. A pleater. With a row of bobbins. Thread, a row of little needles……….. And, it is supposed to sew pleats that are equal. Haven’t had time to do anything but take it out of its’ box and get a quick picture. My brain has been busy dreaming up places to use rows of little pleats…. But, no time yet to experiment with this contraption. This was a gift from a woman who has sewn for decades and is no longer able to see well enough to sew. She had never even tried to use this, but didn’t want to just toss it. So, it has a new home in my studio, waiting for a test run! I’ll keep you posted if I can actually get it to make pleats!
