My dear, animal loving daughter has been asking to make pinecone bird feeders for MONTHS, so we finally collected some pinecones on our last trip to the camp. Here is a step by step pictorial in case you want to try it yourself.
Step 1 - Spread peanut butter on the bottom half of your pinecone
Step 3 - Yell at your brother for putting his rock in the birdseed
(I don't think this step is really necessary)
Step 4 - Lick your completely safe butter knife clean
Step 5 & 6 - Tie with ribbon & hang
