My friend, Jenie, did this with her daughter at their playgroup. Very simple and a lot of fun. Take a bagel, we cut ours in half, but I don't know that that is necessary. Slather one side of the bagel with peanut butter or soy butter. Put birdseed on a plate and dip the bagel (peanut/soy butter side down). Tie a string through the hole in the bagel. Hang outside for the birds to enjoy!
