I take a picture, load it onto the computer, write a short note about it - date, size, occasion or person, approx. cost, anything weird in making it. I have one flash drive dedicated to quilts. Easier to retrieve and much smaller to save than a journal. I am SLOWLY working on getting all my to do list quilts onto the computer and out of the drawers, files, notebooks, stacks....around my workroom. And really deciding if they are really a to do item or just a passing thought!
