It's hard to see, but are you also putting ch1 spaces between the 3 sc in a row? That's the only place there shouldn't be extra spaces. Otherwise, it looks good. If you are putting the spaces there, I'd just go with it and not frog the whole thing. I think it just slightly changes the shape of the wave. Looks good, and I like your colors.
I am not putting ch1 spaces between the 3 sc in a row, so I guess I'm doing okay.
I personally don't like pink much, but I'm making this for a cousin who is a total pink-aholic.
