OK, I had the same problem.....changing needles all the time. So, I took a piece of white felt (you could probably use batting too) and labeled it by brand of needle and size of needle with a permanent marker. When I use a needle, and finish with it, I just stick it in the proper place on the felt. I also have a "sticky" piece of paper attached to my machine where I write the type of needle in the machine at the current time. That way, when I want to change it out, I know where to put it on my felt "caddie". Works for me!!
