I use drum heads.
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.
Used both clear and white Here is a picture of one. I have couple of sound videos with the other. http://www.cigarboxnation.com/video/sunday-beer-break-banjo-blues-f...
