Inspired by https://www.instructables.com/id/Tessellated-Wooden-Art I made a low poly picture of a hummingbird.

Step 1: Things You Need

Materials:

piece of plywood (mine was 12mm sheet)
scrap piece of wood or plywood for the background
spray adhesive or any other glue to attach template to the plywood
paint
wood glue
super glue
wall hanging hardware

Tools:

printer
saw (I used a scroll saw)
sanding paper

Step 2: Cutting the Template

I printed out the image of a hummingbird on two sheets of paper and glue them on a 12mm plywood. I cut each triangle out with a scroll saw. While doing so, I also number each triangle on the printed image as well on the bottom of the wood pieces.

Step 3: Painting and Glueing

I lightly sanded and painted each piece and started glueing them to the wood board. Since pieces are so small I wasn't able to use any clams, instead I used a wood glue with a bit of super glue to hold pieces in place while the wood glue do the magic.

Step 4: Final Product

All in all, I am pretty happy with how my little project turned out! Though, if I would do it once again, I would definitelly use a bigger mesh size, since some pieces were so small that I needed to use a tweezer while placing them down.
