Begin assembly by creating the interior mouth structure, inserting a creased cardstock plate into the toe of an olive-green ribbed sock and lining the cavity with sage-green craft felt. Cut twelve leaf-shaped dorsal scales in varying shades of forest green, chartreuse, and golden-brown felt, snipping small serrated notches along the leaf borders. Glue the leaf scales in pairs back-to-back with a quarter-inch base tab spread open, gluing the tabs along the dorsal spine of the sock from the brow down to the cuff. Snip short lengths of variegated green wool yarn, gluing small fuzzy clusters around the eye sockets and behind the jawline to mimic forest moss. Cut two small curved branch horns from dark brown craft foam, anchoring them directly behind the yarn moss. Sew two large wooden coat buttons onto the upper head to serve as natural, earthy dragon eyes.
