If you try to use cone thread on a standard sewing machine chances are it will not fit the spool holder. A cone thread holder and stand are needed but why spend extra money for additional equipment. Simple solution: place the cone thread on the vertical pin on top of your sewing machine with a small spool inside of the bottom. If your machine has a horizontal pin holder this cone thread trick will not work, sorry. Some suggest to place the cone thread in a cup to stabilize the thread but using the vertical pin stand is the best solution to give your machine an even thread feed without adding tension to your thread.
