How to build a drey

First select your tree - a large oak will be fine. Next, balance on a thin twig 30 feet from the ground, then gnaw through it, catching it in your teeth. Place twig on 'V' intersection of a substantial branch and trunk. Repeat until a platform of twigs is built. Then try finding some twigs which still have some leaves on, add these to platform.

Be aware that you may drop a good number of twigs as you re-arrange them - just let them fall - there are many more above you. While you are building, you may also find it useful, if bored or distracted, to jump 4 or 5 trees away and start building another drey, until you realise your first one looks better.

When finished, climb inside, curl up and have a good nap.
