Craft: Gingerbread bird feeder

For a festive twist on homemade bird feeders, use a pre-made gingerbread house as a base for your feeder. I especially like this bird feeder because it is biodegradable!
 
Materials
-Pre-made gingerbread house
-Peanut butter. Solid vegetable shortening, such as Tenderflake, may be substituted if your crafters have nut allergies. Avoid using natural peanut butter, it is too oily and the seeds will not stick. Inexpensive generic brands work best.
-Spoon or spatula for spreading peanut butter
-Yarn
-Sharp knife
-Bird seed
