This instructable I was inspired by a recent instructables I've seen on this site a few days ago in this page: http://www.instructables.com/id/square-wood-trivet/
Mine is built with recycled materials and easy to find, easy construction, so much so that I made in a few hours of work: this is the typical "weekend project"
Step 1: The cut
If I reproduce the geometrical figure of the Hexagon, I started first to draw on a spruce Strip (sourced from a package), you are exactly identical equilateral triangles, using the wood as much as possible.
For information my triangles have a 70 mm side.
After cutting all blunt edges have sandpaper increasingly end, until I got these pieces as you can see in the figure. cute right?
