How do I make a dragonfly out of ceiling fan blades?

There was a cute DIY on here in the past to make a dragonfly out of ceiling fan blades painted and attached to stairway spindle. There was wire that was wound up on the ends for antenna. My question is what was used to hang these on a wood fence?I would appreciate an answer from whoever knows about this yard art idea as I'm making them for Christmas presents.Thank you so much.
