The pattern I used for the embroidery is one I designed a long time ago and had posted for free on Craftser. I based it on Sailor Jerry tattoos. The card itself measures only 2.5″ x 3.5″, not counting the little fabric border. This piece is actually a very small quilt. The batting is a piece of blue felt. The back is covered by the white fabric that creates the border.
