What do you do, just put peanut butter on them and then roll in bird seed? I have been planning on doing that, but just haven't gotten around to it.
Wife made some a few weeks ago. Buy the cheapest peanut butter you can get, melt it in a large sauce pan, stir in seeds, put on latex gloves and just mash the mixture in the pine cone. You can add a hanger before or after. To do it after just loop it around the pinecone, pull tight and tie a knot, it will embed in the cone. The birds (and squirrels) love them. If you can find suet, you can do the same thing.
