Hope this attachment works:
I found something like this online- someone had sewn this and labeled it and they put the needles they used in the correct spot. I made this spreadsheet out of it and use a push pin on a bulletin board to indicate which machine has which needle. At some point I do plan to sew this too so that I can put my used needles in the correct spot on it. For now I use a marked tomato for that.
For those without Word, I'm hoping you can get the chart here:
