I am thoroughly impressed with the way artist Jennifer Maestre is usings bits of pencils to create her art. I'm not quite sure how she's doing it, but the results sure are beautiful. What a wonderful way to use up those short little pencils that are too small to sharpen or write with. She also uses nails and beads and has sections of her website devoted to that.
