I worked on a project for which I wanted the very best color printable fabric, and tried many different brands. June Tailor, Printed Treasures and others just didn't measure up. By far the best was EQ's Cotton Lawn. They make printable sheets on several different types of cotton fabrics, and I tried all of them for my project. Definitely the cotton lawn. Soft hand, no fading after washing, nice sharp images.
These work only on ink-jet printers. The instructions specifically say not to use on laser printers.
Be sure to practice-print your photo on plain paper until you get your colors just right, contrast, size of image, etc. if you can manipulate these variables on your printer. That way you don't waste the fabric sheets. Be sure you have the fabric sheets positioned the right way in your printer and secure in the paper tray.
Good luck!
