Years ago, I had a wonderful DMC color card with actual samples of all their embroidery thread colors. I used it all the time to choose colors and make a shopping list from. It was one of the things lost in our fire. DMC makes a Shopper's Checklist which lists all the threads by number, but it doesn't show the colors. Plus, when printed up, I found it to be a little too large for my liking.
So this weekend, I decided to make my own little booklet to meet my preferences. Using a small Moleskine Cahir, I wrote down all the DMC embroidery thread numbers from their checklist. Then I went through my boxes of threads and snipped an inch of each color, pasting it next to the appropriate number. If there is a snippet of thread, then it means I have a bobbin of that color. In pencil, I wrote how many extra skeins of that color I have. On bobbins of thread that I need to replace, I put a star. For a couple of thread numbers, I found that I had two bobbins with the same number, but obviously different colors! For those, I simply pasted a sample of each! The booklet is small enough to keep in my purse without adding much bulk or weight and will now keep me from purchasing duplicates of what I already have!
