Ultra fine orange glitter
Elmer's spray adhesive
Using real pumpkins allows you to choose the shapes and sizes you want, but you can also buy plain plastic pumpkins. Also, if you grow your own pumpkins you won't have to spend any money on them, thus reducing the cost of this DIY. I used pie pumpkins for this project and spent less than $1.50/per pumpkin.
Before you start you will want to tape off the stem with painter's tape.
You will want to glitter the pumpkins in sections to avoid having other things stick to the adhesive. I used two large pieces of paper, one I set the pumpkin on while it was sprayed and glittered and the other I used to tap off the excess glitter (which allows you to re-use the excess). Once you're done remove the painter's tape and enjoy the beautiful decorations.
