What can I do with those mini pumpkins?

Every time I see these mini pumpkins in the store, I love them, but when I get them home, I do not know what to do with them. Generally, I set them about on tables and shelves.  I saw this idea via Pinterest and loved it.  There is just something about them hanging and they even weight down the tablecloth so it does not move or blow away. 

The next question is, what material is that cloth made of?  I want it.
