I found this lovely lady's site and videos a while ago and have been daydreaming ever since. I've always wanted to do this kind of thing. I'm not a great swimmer but it looks like so much fun. *^_^*
This is reminding me of how I never have made that swim tail I've craved since I was seven. (My early tries using cut-up inflatable pool beds were not very successful so they don't count. ;) The fabric one my mother made for me when I was eleven was pretty sweet. I still have it, too!
But now. Now I have skillz. And all that leftover ABS sheet. And an airbrush. And, oh look, Denver Fabrics sells 3.6 mm neoprene! XD
