This design has actual measurements of approximately 4¼" wide by 2½" tall (11x 4cm). The stick pin is about 4¼" (11cm) long.
The photos don't really do these justice--I need to experiment to get some better ones. You will not be disappointed. These lovely pins go with just about any sort of knitted garment. A very pretty and functional piece of knitter's jewelry. Great as a gift, too.
