I had the pleasure of test-knitting a sweater pattern for Becky, a very talented knitter and designer whose blog I've followed for the last couple years. A couple months ago she said she was looking for test knitters for a new design and I thought, hey, I've been wanting to knit another full-sized sweater! So I volunteered.
I used KnitPicks' natural, undyed Wool of the Andes worsted weight yarn, dyed to two different shades of blue using Rit dyes, with the contrast left undyed. It was my first foray into dyes other than Kool-Aid, and went pretty well! The yarn is slightly thinner than the heavy worsted suggested in the pattern; I went up a size to #10 needles, which produced a slightly looser, more drapey fabric than the heavy worsted would, but keeps its structure well. I would say if you like a firmer, stiffer fabric, stick with the heavy worsted, but this worked well for my preferences. It knit to the correct gauge on the size 10 needles, and blocked out to the right size. (It's also budget-friendly! The whole sweater took only 5 hanks for the main colour and one each for the two contrast colours. I dyed 6 of the light blue and had nearly two whole ones left over, plus plenty of the dark blue and the white - so my dad's getting a scarf out of the remainder.)
To sum up: this is a really nice pattern! QUICK to knit, very simple, but just enough colour work that it's not mind-numbingly boring; I enjoyed making this. And there are only two short seams, which suits me just fine; I hate sewing in a knitting project! The fit is nice, and both of my picky brothers approved of the design :D Two thumbs up from me!
