Each piece is handmade by Ross of 3 Crows Venture and a few laser gnomes from Birch plywood and finished with natural Tung oil. Each piece comes fully assembled and ready to hang in a window, on your wall, or out on the patio. The Tung oil offers some limited protection from the elements. The colors shift with the angle of the light, so as you move or it moves the interplay of color and pattern changes. Works beautifully as a hanging or sitting art work! Pairs well with sunsets.
