Here you will find a large assortment of personalized embroidered tee shirts designed for Grandma. I use Gildan brand 100% ultra cotton 6.1oz. shirts. They are prewashed by the manufacturer but they do shrink about 3/4" in length and width with the first wash. All sizes are unisex. Each shirt listing may have different color selections according to what looks best with each design. I have a special section on the left hand side and bottom of each page titled "Tee shirt colors" where you can see the colors.
