In search of the perfect pattern

I have been searching for a sweater pattern, and I came across this one and fell in love. I did some swatching last night and the yarn knits up beautifully, but I think the pattern may be too busy for the yarn. It's hard to tell on such a small piece, but I am not sure I like how it is coming out, so I may save the pattern and use a different yarn. In the meantime, I am back to the drawing board. The variegation in the Jubilation yarn is such that it changes every 3-4 stitches, so I think I am going to go for something more simple. I have this idea in my head which I think will work, though I don't have a pattern for it, so we will see how it goes.
