You’re right, human skin is much less ewwer. 
“Speaking of Obscura, I happened to click by on the channel and saw a guy selling a human skull encrusted with Buddhist symbols, stones, etc. Damn if the husband doesn’t actually own one of those! Proudly displayed between the shrunken head and a stone carving of a warriors head, from Timor. But I didn’t see either what they paid for it or what they’re selling it for, and you just know he’s dying for that tidbit of info. Anyone see the show?”
I don’t specifically know a lot about Buddhism however many Hindu monastic orders practice water burial and you can easily find their skulls along the Ganges, some monks or yogis will us them for certain rituals, I’ve seen them for sale in the west maker a nice incense ash holder I suppose.
A creepy shrunken head… to display next to your creepy mummified corpse… uff creepy.
The OP hasn’t been active since 2006, I wouldn’t hold out too much hope for an offer.
