Wanna leave your mark in a cool but unobtrusive manner? How about a mossy message for the masses? Grab a clump of moss, whip up a moss milkshake, apply, and watch your art grow. Helen Nodding shared her recipe with us way back in CRAFT Volume 04, and it’s a perfect flashback for Natural Materials month on MAKE (and ideal with all the rain we’ve been getting this week), so we shared the how-to in Make: Projects. What will you tag up in moss?
