Have you drooled over the Robert Kaufman Kona Cotton Color Card like I have? I've drooled, but then gagged on the price. I've been purchasing a lot of solids lately and decided to create my own color card.
I just cut a little scrap of each color about 2" square (usually AFTER I've used the fabric for a project to make sure I have enough), stitched it onto an index card, and wrote the company and color name on the card. A hole-punch and book ring holds them all together.
I'm not caring that they're sewn on perfect, and some of the scraps are different sizes (just what I had left), but the samples are bigger than the 1" square on the official card. This will be especially fun as I receive my "Solids of the Month" from Pink Chalk Fabrics.
