I'm very excited b/c we bought our first house in July and I get to decorate it for Christmas! I was looking at decorations the other day and overhead a woman say that wreaths and garland with the artificial berries aren't good for outside. The berries swell and burst and you're left with exposed white foam. Before overhearing this, I was leaning towards the berry wreath and garland -now I'm torn. Is there something I could spray them with, like a clear acrylic paint, that would prevent this from happening? Thanks! Micki
