For my first foray into these pages I chose the first and simplest pattern: a fish, but added details of my own. I will move through the book to the more difficult gusseted creatures sometime soon.
One thing to be aware of for these patterns is that there are no seam allowances included so you will need to add them when cutting your fabric.
For the top fin, stitch the open side closed before quilting the lines in order to prevent the stuffing from getting pushed out. I continued this line of stitching all around the fin, following the curves at the top. Then I followed a similar procedure as for quilting the side fins. I added a little more interest by curving the lines of stitching slightly.
Note: Looking at pictures of fish fins before doing this helps to get a more realistic look.
