This is a set of home sewing machine needles. I am selling them because I changed sewing machines. Needles: size 7 (10 needles), size 9 (5 needles), size 11 (5 needles) size 14 (5 needles), size 16 (5 needles) size 11 for knit (5 needles) Leather needles mix: size 11, 14, 16 All are unused. Would these be suitable for someone who wants to have a variety?
