Wow, I did it, read through all 138 pages of tails.
I made these between 2007-2008 for various parties in SF. They weren't swimable! The flukes are made out of up cycled couch cushions that I carved and made foot pockets in so we could flip them around. Gosh those were fun times! But of course that was before having all the kids, and settling down

The gold tail is a latex fabric, and has a very cute attached top with keyhole stomach and back area, very pinup like. The Mahina monofin isn't sealed in so I can walk in it. I just made this one last month.
I am working up a design for a silicone tail, and can hardly wait for hat to be done so I can post here again
