even heavy mil plastic like tyvack, might work initially, but first time you accidentally press a finger or anything into it, it will stretch the plastic in that spot, make it look like doody on a stick and start to effect sound quality.
no rose , never tried tyvak.
I just watched it as well, enjoyed it...now, about that neck, how long is that thing, what kind of scale, looks like you could take that instrument into battle if you had to lol ;-)
yup that thing is thexah . ;-)
I'm building one as well in the next few weeks, I'm using a 12" tambourine drum head for mine, has beautiful sound, and is animal skin unless your initial reason for not wanting it to be animal skin was personal.
and this one doesn't have the cymbals to remove, inexpensive on eBay, took a little while to get, a couple weeks, but worth it in my opinion, especially the cost, saves a lot of work too. Let me know if you want the url to check it out online
