Brian,
I've got one that was in BH&G's Wood Magazine about 8 years ago. I made it for one of my kids and would be glad to send the pattern to you, snail mail, if you'll send me your address. If you don't want to post it here, email me at
dcthomas@hotmail.com.
There is at least one or two books out there about carving Kachinas. But I've only done the one that was featured in that magazine. You're welcome to it if you want it.
