Franks Blanket is in two sizes - small (approx 50cm) and large (approx 70cm). The small blanket uses 2 balls of the main colour and 1 of the contrast (for the Dachshund - Frank); the large uses 3 main and 2 contrast. Both sizes use a small amount for the ear and a length of black for the nose and eye.
Any yarn can be used and tension isn’t important, just be sure you have enough yarn to finish.
