I'm a big fan of Ed Emberley books. These are drawing books for those looking for directions (if you are not the most imaginative person) and ideas. My favorite of his books are the ones that show you what you can draw when you start with your thumbprint.
Start with a washable ink pad, a couple of fine point sharpies and paper. If you have a couple of colors of ink pads, that's even more fun. The books are Ed Emberley's Great Thumbprint Drawing Book, and Ed Emberley's Fingerprint Drawing Book. Both of those books are combined into a third book.
After you have made some drawings, think about bookmarks, or funny cards. After all, Valentine's Day is next week. This would make a fun craft idea, or special cards for classmates. The books are on the shelf this week at J741.2 EMB - check them out today!
