Thank you for letting us know that these strong magnetic bowls need to be place far enough away from the computerized sewing machine, very good advice. I purchased two very pretty, small bowls from a garage sale, for this purpose, they measure about 4 inches wide by 3 inches long, they only hold about 25 pins safely, any more and the pins fall out .We don't have a "Harbor Freight" store in our area. I used 3M mounting tape to adhere the magnetic's to the bottom of the bowl. In all fairness to the gal that posted this note, I still plan to use the idea, but will move it far enough away.
