The trend of the future is larger thread spool sizes. Traditional machine spools cannot hold as much thread as the cone-shaped king spools or mini-king spools. Much of the cost of a spool of thread is in the winding process so the larger the spool, the greater the savings. If you use a cone shaped spool with a large opening in the base, it won't fit on the standard spool pin holders on most machines. Since machine manufacturers have not yet caught up with thread manufacturers, you will need either an adapter or a thread stand. The thread stand is advantageous over other home remedies such as a mason jar or tall glass because it stabilizes the thread and elevates it higher than the machine. The vertical arm of the thread stand lifts the thread higher than the machine which then facilitates an even feed without added tension. Thread stands can accommodate any type of thread which is wound on a cone, king spool or mini king spool. The thread on these spools is cross-wound, and is intended to pull off over the top as the spool sits flat on the thread stand. Cheaper thread stands are all plastic and sell for about $8.00. They are lightweight and may tip over during use, causing more frustration than help. For an additional 5 or 6 dollars, you can buy a heavy duty metal base thread stand that will serve you well and allow you to buy larger cones of your favorite threads, thereby saving you money. A good thread stand will pay for itself over and over.
