This was so fun and easy to make. Very inexpensive also. Makes a cute Halloween decoration for the shelf!
All you need is a glass (I got mine from the dollar store). Some glue and a skewer. Then I got the eyeballs from Michael's craft store.
Pour it into the glass.
Put the eye on the skewer and let dry for several days.
I added a little photoshop to this last picture for some fun Halloween effects. :)
