I recently "modded" a jungle hat that I've been using for kayaking. Since the hat has survived, sun, sea and washing machine cycles to become well seasoned, I don't really want to lose it. Even if it only cost me $7 and is easily replaced.
Most of us know that when a cap or hat drops into the sea, it floats for a while, before sinking into the abysmal depths of the ocean. An offering to King Neptune.
So... to get to the point, I "modded" the hat with a little fishing net float that cost 15 cents. I got this float from a wholesaler opposite The Concourse near the Malay Heritage Centre.
They come in a many different shapes and sizes too.
Here are some pics.
