Hi all, I am a newbie! Using melt & Pour! I have purchased beautiful little craft boxes to put my soap into with ’sniff holes’ and would love to be able to use them, however shrink wrapping seems to be the only way to prevent the sweating. I have put the soaps in these boxes but they have sweated and left oily marks on the craft box! Is there any other ways I can prevent the sweating and use these boxes?
