It looks like cheese cloth to me or tack cloth. Check it out at your local hardware store. Since the material is sticky it will stay in place. Dust one side with baby powder so it stays white and is not sticky.to the touch.
Obviously I’m guessing but that’s what I’d try.
@LuckyGuy I thought it was cheesecloth, too. My mom said gauze, as well, but I am attempting to pull apart a roll of gauze that I have on hand… and it’s not happening so smoothly.
I guess any would work.
I had to run out and get some office supplies so I checked the gauze. The biggest size was 4“X4”. I guessing that is a single sheet of cheese cloth. The hair spray idea sounds good.
(Anyone else find her totally hot, or am I just disturbed?)
@LuckyGuy is right. It looks like cheesecloth for sure. You can even find it in the grocery store this time of year. Lots of people use it at Thanksgiving time. Hairspray is a good idea but if you want it even stiffer you can use a craft product like this or like this
