Important Sewing information
Correct needle/Thread combination
To sew optimally, the thread should travel smoothly down the long groove on
the front of the needle.
Too thin thread or too thick needle
The thread has too much clearance in the long groove. Skipped stitches and
damage to the thread can occur.
Too thick thread or too thin needle
The thread rubs on the edges of the long groove and can get jammed. This
can result in thread breakage.
