How do you thread your machine for a triple needle?? Check your machine's manual as the threading method does vary between machines. In most cases you will use two regular thread spools on the machine's two spool pins. For the third thread, fill a bobbin and put this on the second spool pin under the regular spool (with a spool disc to separate them) - see photo!
