I wish I would have ordered this item years ago. I tried making a note of which needle I had in the machine, and sticking in on my machine, but sometimes I would forget, or the note would fall off. And since I don't sew everyday, I never was sure what needle was in there.
I which there was some way to identify needles by more than the size, but I know they are too small, and with all the manufacturers, and all the different types, there could never be a standard.
