Tie a length of string around the top of an open pine cone (it should open when dry).
Using a knife, carefully smear the pine cone with a thick layer of specialised unsalted peanut butter, which is available from various retailers.
Put a birdseed mix into a bowl. Roll the pine cone around in it until it is coated in seeds.
Hang the cone from a tree or a shrub. You can also string several cones together.
