Toast a slice of thick bread lightly. Alternatively, use a stale piece.
Cover one side of the bread with peanut butter and the other side with suet or you can cover both sides with one or the other. Peanut butter and suet attract different kinds of birds, so using both will draw the greatest variety.
Pour the bird seed onto a plate. Push the piece of bread lightly down on to the seed to make the seed stick. Turn it over and push the other side into the bird seed.
Poke a hole in the center of the slice of bread with a pen or other pointy object. Thread a string through. Hang the cluster on a tree.
