Update on myself, as well as the first post (I'm writing this before the first post update)
I have decided to do a Halloween Town Kair to match my friend's Halloween Town Sora. Since sora has a "Jack Skellington" related Keyblade, her and I thought maybe a "Sally" related keyblade for Kairi. Here's my design so far (I haven't got the teeth designed yet):
It's essentially a giant sewing needle with red yarn threaded through it..Then the yarn wraps around the handle. It will be more wrapped tight to make the grip, this is just so you can see the basic idea..The parts at the top of bot sides of the handguard are going to ne painted to look like the hill..I might put the fences and pumpkins on it..Still thinking of what to do fo the teeth..
