Easy inexpensive yard ghost

I'm sure there is a thread about this somewhere but I couldn't find one. I'd like to make some inexpensive yard ghosts for the yard. I saw a DIY on utube I like using tomato cages that looks pretty easy but was wondering if someone had any other ideas on how to make them and had pictures or easy how to instructions. I just want something simple that won't cost an arm and a leg to make . Would appreciate any help!
