Two four inch diameter logs are split in half to form the legs. One end of each leg is reduced to a wedge shape as you can see below.
Once all four legs are in, you can cut off the bottoms of the legs to achieve the ideal height.

Now bend the long piece at a ninety degree angle to the mouth piece and then curl it around to form the air chamber and you should have a shape rather like a question mark.
Place your thumb over one side of the air chamber to form a seal and your index finger to seal the other side, just leaving the narrow opening immediately after the mouth piece. Ensure the gap at the front of the mouth piece is wider than that at the back (this will take some adjustment and experimentation to get right), then blow!
Gather five sticks roughly the same length as you’re height. They should be about the same diameter as a pencil at the narrow end. Remove any side branches and then the bark.
Now using either a piece of ribbon, cord or elastic lash around the shoe and over your toes, tying the two ends on top of your toes as shown below.
The snowshoe is easier to use if the tip of the shoe curves up at the end, so tie a cord between the tip and the block of wood and leave until the wood has dried out.
