Primitive Large Wooden Chunky Leprechaun Derby Hat St. Patrick's Decor. LOVE LOVE LOVE this. My Dad created these large chunky wooden leprechaun derby hats for a special customer. They will now be a regular, so cool. These stand up nicely. Solid wood with metal buckle, which will vary as they are repurposed. Hat is painted and distressed in dark green with a grey band around the brim and a little burlap clover towards the top. Size is 9" high x 11 3/4" long x 3 1/2" deep.
