A Boo to You!
I saw this idea a long time ago on Pinterest. I went back to look for the card, to give credit to the original creator, but I couldn't locate it again.
You can put anything in a jar! Use sticky notes to create some masks and away you go.
I am entering this in the H2H Challenge - Wood you rather? CTMH has a great new set of wood papers - I just haven't ordered any yet. The wood grain table on this card is from an older paper pack.
