As I made each purchase, I printed off the design and thread color then I put them into a notebook. I have each card reader filled with each section of my notebook. Example: designs for Christmas, card reader 1.
Bird design on card reader 2 etc. the notebook is divided into sections with tabs that tell me what it contains and which card reader I can find it on. The order of the notebook designs and the designs on the card reader are the same order. On my machine the design shows up so small it's hard to see so I can just count to find the coordinating design on the card reader.
