Hi gang. I'm seeing shrink wrap metioned but it's all Dutch to me. If I were to do votives and pillars, would you still be able to smell them??? Also, would I buy tubes or bags and would I need a heat gun similar to what I have to heat molds and so on, or one of those bar sealers that I see. Further, if I were to use the baggy things then does it make the wrap all tight like a skin, with the heat gun.
