Super fast full-head animal hat instructions;
1 at a thrift store or garage sale, find a stuffed animal you like whose head is roughly the same size as yours.
2 Cut its head off, at the neck. Including a little more of chest/head transition makes good chin tie.
3 cutting out the snout and eyes makes the face hole. Cutting close around edge of eyes makes a V shaped "dracula" look.
4 glue gun or sew rolled edges. Customize ears with light wire for bendable expressiveness.
5 the hind and two lower legs can make an interesting hat with a little button tail on your forehead. Just cut at the belly line.
Play with it, do a few, get creative with customization. Pick a few that are smaller, give them to kids you know, they love them. Also if you attach a light bennie or baseball hat with brim removed,on the inside, it can be more comfortable.
I have also skinned an entire mid sized toy tiger and worn the head as a hat with the pelt going down my back. Very shamanic looking.
second hand stuffed animals are a cheap faux fur source as well.
