Download the PDF template right here (it makes two coasters.)
Print out the pattern and pin it to a piece of felt. Use an X-acto knife (press hard) or a rotary cutter to cut the diagonal slot in each pattern piece. Then cut apart the pieces, adding the cuts on the sides.
Grab four of the pieces and orient them as shown above. Each piece should be rotated 90 degrees from its neighbor, so that the ends with "arrows" are chasing each other around a square. Pull each arrow through the adjacent slot from the back to the front.
The coaster will look like this when you've locked all the pieces together.
Trim off the points of the arrows. Also trim off any edges that stick out so you end up with a neat square.
To make a larger trivet, see my next felt project.
