Every January, I turn all of the hangers in my closet backwards, like this. It takes about 60 seconds: Each time I wear an item, I hang it back up in the normal fashion, which takes zero effort to remember or do. In June, any item that is still hanging backwards has not been worn in 6 months, and I usually donate it to Goodwill unless I can come up with a good reason to save it.
Mix peanut butter and vegetable shortening; melt in a microwave for 1 and 1/2" minutes on high. Mix in quick-cooking oats, cornmeal, and flour. Pack mixture into two paper cups, then cool. Remove from molds, and place in mesh bag, plastic clip side down. Secure open end of bag, and hang feeder from branches at a good height above ground.
