Spools are usually wound with a straight grain or parallel wind. The thread is intended to unwind in the same way as it is wound onto the spool--from the side, not from the end. It does not matter if the thread unwinds from the front or back of the spool.
- If the thread is a metallic or other sensitive thread, it is usually better to place the spool on the vertical pin spool holder and have the thread unwind straight from the side.
- If the thread is poly or cotton and works fine when positioned on the horizontal spool pin, there is no need to change it to the vertical pin spool holder.
The trend of the future is larger thread spool sizes. 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. What's the solution? A thread stand holder.
The thread stand holder stabilizes the thread and elevates it higher than the machine to allow for even feed without added tension.
