FABRIC, THREAD, AND NEEDLE COMBINATIONS

Note

● Never use a thread of weight 20 or lower. It may cause machine malfunction.

Memo

● The lower the thread number, the thicker the thread; and the larger the needle number, the thicker the

needle.

■ Ball point needle

Use the ball point needle when sewing on stretch fabrics or fabrics where skipped stitches easily occur.
The factory recommended needle is “HG-4BR” (Organ). Schmetz needles “JERSEY BALL POINT” 130/705H SUK
90/14 may be used as a substitute.

■ Transparent nylon thread

Use a 90/14 to 100/16 needle, regardless of the fabric or thread.

●

Make sure you follow the needle, thread, and fabric combinations listed in the table.
Using the wrong combination, such as heavyweight fabric like denim with a small needle
(65/9-75/11), may bend or break the needle. The wrong combination may also cause the seam
to be uneven, the fabric to pucker, or the machine to skip stitches.
