If you want to do it with book pages, here are my instructions (which I haven't really tweaked yet - just wrote quickly for my Facebook friends).
Those of you who are interested in doing this project, but are not patrons at my library, here's what you need: 12 inch cardboard circle. 110 4 X 4 inch pieces of book pages, 10 3 X 3 pieces of book pages, a bit of twine, and a hot glue gun. Cut your hole for the twine hanger prior to beginning to place the cones.
Fold you book page pieces into cones and hot glue them together. Start by placing your first cones about 1 inch in from the outer circle, about 3/4 to 1 inch apart. Place your next row of cones in between these, about 1 more inch in from the first row. Continue until you reach the middle, where you will switch to the 3 inch paper cones.
