I love my Brother. I found her at an estate sale for 25.00. Runs great and looks even better. I've heard louder zippers then this little beauty. Somehow I have lost my bobbin case ...does anyone know if it takes a regular class 15 case or do I have to order a special one for this machine? I used one from my Singer and for some reason,[ATTACH=CONFIG]599292[/ATTACH] the upper thread would not pick up the bobbin thread. I tried changing needles, re-threading and using a different bobbin...nothing works! Any help will be greatly appreciated!
