HOW TO CHECK NEEDLE?
If you sew the fabrics which are susceptible to damage (knitted fabrics particularly) and you are not sure if the needle top does not damage the fabric, please make a following simple test. Prick by needle the stretched (old) tights, and if the tights do not ladder, you can sew without any doubts.
Needles should be stored in original boxes - never loosely!, because it causes the top damages, what makes the irreparable fabrics defects.
