I just found these. I have made my own cards for yarn, stamps, ribbon, paint and lists of how much yardage needed for items but not for fabric swatches. I haven't needed to because I do a lot of patchwork and it doesn't matter too much. Also because I don't really do matching quilts. This is perfect if you want to match your fabrics for quilts or dress making. I know you can make your own but sometimes it can be easier to just buy it and get it done quickly.
