I recently was asked to crochet a photo prop based on this pattern by Wichecraft. I mostly followed her instructions exactly, although I did the reverse on the flippers and increased instead of decreased because I wanted the right end of the flippers to face a certain way when folded over. But really, if you do the pattern as written you'll get it!
Here's my finished project:
I can't wait to see pictures of it on the babe!
