I don't know why I am currently so in love art using stones, but I found these gorgeous stones covered with intricately patterned ink drawings by artist Yoran Morvant.
I want a whole pile of these bad boys.
My work references rocks and stones a lot, since they were the first thing I ever obsessively collected as a child. The juxtaposition of graphic elements with natural ones has been something I've always struggled with, but I couldn't think of a more elegant way to interpret that than adding graphic elements on a natural surface. Beautiful.
You can buy these at Ashes & Milk.
