Threading Tips and Hints

There are many threads on the market today developed for different purposes. The quality and structure of the thread as well as
the shape and size of the thread spool can affect the behavior of the thread. Threads can also behave differently if the spool is
full or nearly empty.
If experiencing problems, try the tips and hints below.
Note: Always test sew on a scrap piece of fabric to check the sewing result.
If the Thread Spool is Pulled up on the Spool Pin
When the thread on the spool is running low, the thread can
snag on the edge of the spool and pull the spool up on the
spool pin. Place a spool cap on top of the thread spool to
keep it in place. Always use a spool cap slightly larger than
the thread spool to prevent the thread from snagging. The
flat side of the spool cap should be pressed firmly against the
spool. There should be no space between the spool cap and
the thread spool.
If the Thread Slides Down on the Standing Thread Spool
If the thread is of a quality that unwinds easily and slides
down on the standing thread spool it can get caught under
the thread spool around the spool pin and break. Place the
large spool holder on the spool pin with the flat side up
before placing the thread spool.
If the thread spool has the same diameter as the large spool
holder, place a thread net as illustrated from below over the
spool before placing it on the spool pin.
Note: To prevent snagging or increased thread tension on the thread, the
thread net should cover the lower part of the thread spool only, not the
top where the thread spool narrows.
If the Thread Tangles or Curls when Unwinding from the Spool
For smaller spools of specialty thread, the main spool pin can
be used in tilted position, allowing the thread to roll off the
spool.
Place the thread spool on the spool pin. Do not place a spool
cap on top of the spool as it may prevent the spool from
rotating. Pull thread up to the telescopic thread guide and
thread as described under Threading the Upper Thread, page
38.
