Here are my 2 versions of the Wendy Whale pattern that I believe is from a Knitting & Crochet magazine.. I am not 100% sure as I have downloaded the pattern and it is on my hard drive. But it does state its from Lets Get Crafting - which is the people who do the Knitting & Crochet magazines.
I did the blue one first and my friend at the time had sewn it together for me. I then decided to make the pink one and this time I decided to sew it up and sewn the fins on differently than what was done the first time around and I prefered the way that I had sewn on the fins compared to the original pattern.
