I now will only use the 100% Egyptian Cotton thread from Conecting Threads. My old Kenmore didn't like the Guttermans, and the Coats and clark is just way to linty. I have a ton of that and just got a bunch more from a friend who's mother passed last spring. I use it for hand sewing like buttons and such. Most I will be donating to the Girl Scout Day camp I work at during the summer.
