I am on the first green part at the bottom of the page and it seems to get wider there.
They start you off with 135 stitches then seems to increase to 202 stitiches at the part I am at now. I hope it doesn't increase more. Maybe it will decrease once you do some other gathering thingy.
I didn't read through the pattern. I am just going line by line.
The colors are very pretty so I couldn't resist not making it. It needs a yellow duck now. lol
