This pattern was so much fun to make! This one was the last one I made and it was a nice refresher after the fish fiasco. Let me warn you, YOU MUST PAY ATTENTION TO WHAT YOU ARE DOING. Eventually, you establish a pattern to the wave, but until that point you can't let yourself get distracted. This pattern is really well written though, so it shouldn't be a problem. She even has a handy dandy YouTube video to help you out.
My only suggestion is to print out the available PDF and highlight as you go. Oh, and don't let anyone talk to you while you're establishing the waves. :-)
