This Pin is two layers, the bottom layer being the interior of the owl emporium and the top layer is the window sill. Resin was added to each four window panes and feather shaped glitter placed before it cured. Each window is decorated with a hand made sign glued on by E6000. Each window is unique and handmade so please be aware that there may be minor flaws, as it will not be machine perfect. Windows are 60mm wide and have two posts on the back.
