well I found a package of kenmore needles that were with the machine... they are color coded, I checked the chart in that other thread, and no clue what the numbers mean and what would be good for cotton wovens.
Kenmore color codes
Kenmore colors its needles with a different system of color codes which indicate the needle's size:
Shank color Shaft size Shaft size (europe)
blue 11 75
orange 12 80
red 14 90
purple 16 100
green 18 110
I have one of each of these... which one should I use?
