I use a tomatoe pincushion and mark the different sections with needle numbers that I use.. 90/14, 80/12, metalfil, 75/10 etc. when I take a new needle out and put in machine I put a saftey pin into the pincushion in the section that corsponses with the needle number. that tells me what is in the machine. Does that make any sense?? Here is one but, I made my own.. Cheaper~~~
