Cross Wound Vs Stacked Thread

Do you know the difference between cross wound and stacked threads?
Do you know that threads can be wound onto spools one of two ways?

How you position your thread onto your sewing machine is important and can make a difference to your sewing experience. Sewing thread can be wound onto spools in two different methods:

Stacked Thread
Stacked threads are wound onto the spool horizontally, the thread is parallel to the spool.

Cross Wound Thread
Cross wound thread is wound onto the spool in a zigzag design so that the thread forms an X up and down the spool, (seen in Gutermann threads.)

How does the position of these threads on the sewing machine effect usage?
Do you find your thread catching on the sewing machine?

Generally speaking stacked thread should be placed on a vertical spool pin on the sewing machine. The thread should leave the spool at a RIGHT angle, in line with the direction of the wound thread. This will stop the thread catching on the grooves at the end of the spool. Positioning a stacked thread on a horizontal spool pin will cause the thread to catch on the end of the spool pin, causing tension problems on the sewing machine as the thread becomes tight, potentially snapping.

Cross wound thread works best coming off the end of the spool. Cross wound thread can be position on a horizontal spool pin, or a vertical spool pin (if it is situated low at the back of the machine so that the thread comes off the top of the spool).

If you are using a cross wound thread on a horizontal spool pin be sure to use a spool holder (use the size closest to the size of thread spool you are working with). The spool holder will stop the thread from falling off the spool pin when sewing on the machine. Position the spool holder tightly onto the spool pin. Should the spool holder be position too loosely the thread can fall between the spool and spool holder causing tension problems as the thread becomes caught and tight, potentially snapping.
