Hawaiian Shirt PatternThe print is sized at 4"x12" and is beautifully laid out on 3 8" thick Baltic Birch Wood, designed and printed locally in Hawaii. Much research went into finding the right wood to print on. Baltic Birch was the ideal choice due to its beautiful wood grains and sustainability. Printing on wood gives each piece a retro feel, and for each print, the wood grains are slightly different, offering a unique finish for every design.
