These buzzards were so easy to make. I used medium weight black scrapbooking paper, transferred the outline with a chalk pencil, and cut out 3 at a time with a pair of kitchen shears. You can use a craft knife, but I would not suggest cutting through more than 2 at once. I taped them to the window and the storm door, however, you can see the tape. I have to buy some removable adhesive and adhere them that way, but did not have any on hand.
