Lenshoods.co.uk offers up PDF templates for making your own papercraft flare fighters
For a while, I was using one of those sleeves you get on a Starbucks coffee as a lens hood. It was wrapped in black tape and it wasn't pretty, but it got the job done and it was free, which was really important at the time. Had Lenshoods.net been around back then, I could have just printed one out. It's not as cool as the Flower cap/hood, but you can't be the price.
