To start, cut an apple in half. You don’t need to core the center of it, but do make sure you can thread a piece of twine/jute through it.
Spread peanut butter on the apple half. I like to cover the front and the back.
Dip your covered apple into birdseed and press lightly so the seeds stay in place.
Tie your thread into a knot if you haven’t already and hang them from a tree branch or fence post.
