My first thought when I saw the title was something that a person can see through...then I saw your username and I thought of a clear jar...such as I think I have SU jar with bugs...or the pill jar that i saw Cook22 use on a card recently...
SO...is it okay to go with that thought though I wouldn't use acetate on my card?
