Very sweet. I'm just a beginner and haven't attempted anything more complicated than a pair of mittens yet, but I have already frogged almost every project at least once. I feel your pain -- but I your end result is well worth it.
Here here. I've only attempted hats (could anything be easier than a bunch of circles?) but I still manage to get all confounded.
I love the cardigan though! Your daughter looks really really cute in it too!
