This Halloween project is a lot of fun for the whole family. All you need is a clear jar, some tissue paper, and modge podge (Modge podge can be purchased at Wal-Mart or crafting stores. I have made my own and tried it on the jars, but it doesn't work as well--the tissue paper wrinkles a lot more with the homemade modge podge.)
Start by cutting your tissue paper in about 3 inch strips. If you try to paste too big of a piece of tissue paper on the jar it will wrinkle.
Spread modge podge on the jar. I used foam paint brushes for this application. Place the strips of tissue paper on the modge podge. Spread on another layer of modge podge over the tissue paper. For the faces, cut shapes out of a different color of tissue paper and apply those with modge podge as well. After it drys, you can tie ribbon around the top for an added accent if you like.
They look really neat at night with a tea light lit in the bottom of the jar.
