Unbirthday Hat

My hat for the deviantART (un)birthday contest. Items from my "understanding" of the riddles from the previous competition.

Birthday Hat- ContestYou may have heard there will be a BIG unbirthday party and everyone from Wonderland, as well as all deviants, have been invited by the Chesire Cat! A hat will be required to take part though and  it can't be just any random hat, it needs to be special! It must be made for this occasion, on your own and not by or for someone else!. Without the hat, you can't join the party and enjoy all the cake, drinks and fun.
Even if the Chesire Cat doesn't help you, the inhabitants of Wonderland will do or already have! For every hat you have found or will find for them, they will give you a clue. These clues will give you hints of things that must be included, in whole or in part, on the hat. The more clues you get right, the closer you will get to the perfect hat for the unbirthday party.
Combine them all and create your very own birthday hat based on their hints! You should try to include 8-10 clues to make sure your hat will be accepted for the party.

The backwards letter:

There's a snail
Living in my hat
His window
Makes a draft
I like my snail
He's a nice guy
