This is what I sent Shauna for the Ravelry Earth Day swap. Thank goodness she liked it (despite my inability to spell Dreamsicle correctly).
I sent another swap out before this one and the recipient didn't like the yarn I sent at all. I felt bad and offered to replace it. Why would you tell someone you didn't like what you'd received unless you wanted it changed? This person didn't. All I can learn from the situation is if I have any doubts about what I'm sending, don't send it.
