Loved remixing this- this birdhouse reminds me of Dr. Seuss :). I made to template slightly smaller to fit my 12 x 12 materials. Note there are 2 canvases! So the rest of the parts to cutout are on canvas 2.
See the original template for full instructions! Once cut I used wood glue to hold together. I handpainted using acrylic paint and then used FlexSeal to waterproof it. It still looks great!
