Trivet is always needed in the kitchen or anywhere else where you drink hot coffee. Here’s a cool and modern way to create a modular trivet that looks cool and original thanks to the geometric pattern. Print out as many sheets as you need, pin them to a piece of felt, and use a rotary cutter or X-acto knife to cut the slits in each shape. Then cut apart the shapes, adding the notches around the edges. Begin locking pieces together by pulling the arrow-shaped tabs through the slots from the back through to the front side. To finish the trivet, trim off the excess felt around the edges and nip the points off the triangular tabs.
