Needles, Threads; Correct Needle/Thread Combination; Too Thin Thread Or Too Thick Needle; Too Thick Thread Or Too Fine Needle - Bernina 710 Manual

needles, threads

correct needle/thread combination

When sewing, 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 fine needle

The thread rubs on the edges of the long groove and can get jammed. This
can cause thread breakage.
