What to do when you're stuck...
Take a break with some pleasure knitting!
In my case, it's Melissa Wehrle's classic modern knit, the Urban Wrap (with a great kit available here). Although I do love the Lanas Puras Worsted (I used it for my Hexagon Bag pattern), I decided that I wanted to try a yarn I've been hearing a lot about, Dream in Color's Classy yarn. After seeing this beautiful Wisteria in the Black Parade colorway, I was struck with instant yarn lust. Luckily, the Spiders had given me a gift certificate to Knitty City for my birthday and they had tons of Classy in Black Parade in stock - enough skeins to let me choose the perfect ones with just the right amount of variation.
I've done two sleeves (one blocked) and the piece on the needles is the left front. I almost always do a swatch, but I find my tension often changes for a bigger fabric; so I usually block a sleeve or part of a front in order to recheck my gauge and make sure all is progressing as expected.
