I've been collecting pebbles and smooth stones for a long time. (I have a particular fondness for heart-shaped ones.) I love to carry them around in my pocket and hold them in my hand, turning them over and feeling their smooth, round shapes. I even write words on them, so that they become talismans of sorts. The other day, I noticed I'm not the only one who does this.
Check out these stones over at Geninne's place. She's an amazing illustrator in Mexico whose blog is a favorite of mine. I hope she inspires you, too!
