SEWING HINTS
SEE THAT THE PRESSER FOOT is securely clamped by the screw and snug against the
presser bar so that the needle may pass through the opening in the foot without any interference.
SKIPPED STITCHES may be caused by a bent or blunt needle; by incorrect setting of the
needle: the wrong size needle: by a thread too heavy for the size of the needle.
BREAKING NEEDLES are usually due to pulling on the work, causing the needle to get out of
line and strike throat plate, thus breaking or bending the needle.
It may be due to presser foot or attachments not being securely fastened to presser bar.
Be sure to use the correct size needle and thread for material.
