I’m pretty sure these sleeves are playing a joke on me. Check out how slanted they are: 
This has happened to me before. I don’t know if it’s just the moss stitch, or because I knit continental, or what. My Minimalist Cardigan had the same issue with each piece, but straightened up with a nice wet block. But right now I feel like these sleeves are snickering at me.
I reworked the sleeve caps, decreasing every third row after the initial bind off rows, and I added about 4 extra rows after that. Then I finished the decreases as written. I held them next to the finished back piece and felt more satisfied that this thing would work out. I haven’t figured out yet why the front will be 2 inches shorter overall than the back, but I’m going to do it as written and see what happens. Many many many others have been successful with this sweater, so I’ll trust the design. 
I resisted the urge to cast on for the adorable little fox hoodie and instead cast on for the front of the sweater yesterday. I wanted to push through the twisted ribbing at least, but I ended up getting through one repeat, with some weary hands by the end of the night. I watched a couple of episodes of Vera, a detective show on Hulu Plus that I recently learned about. It had a nice level of mystery, without the extreme amount of gore seen in some crime-related shows. Plus, I love the accents. It was the perfect backdrop for some fall sweater knitting.
This post happens to be my 300th post of the blog! As of October 20th I will have been blogging for 7 years. I was very sporadic in the beginning, but at some point it became more intrinsically rewarding and I got addicted. I really appreciate how many people regularly read and comment. I don’t always get a chance to respond to your wonderful comments and input as often as I’d like, but I love how blogging can feel like a conversation in that way. Writing this blog, reading others, and interacting with each other makes my knitting and social life rich and full. I adore the online community and connectedness formed through platforms like Ravelry, blogs, and podcasts. Thanks for being a part of it.
Maybe it has something to do with whether the row starts with a knit or purl stitch. The right-hand edges look quite a bit firmer. I’m sure it will block out fine!
…and congrats on reaching your 300th blog post!
Yes, one side does seem firmer, but luckily it will all be sewn together and no one will be the wiser. 🙂
Congratulations on your blog milestone!
I would cry if that were my sleeves. I HATE knitting in moss stitch, I always screw it up when my mind starts to wander which happens often because the k1,p1 drives me batty! I hope you can block these straight!
Wow, congrats! 300 posts is a lot!
I love how moss stitch looks– it’s such a nice texture! And thanks for the recommendation of “Vera”– I’ll have to check it out! I love detective shows, too, but not so much the blood & guts.
Whoo! 300 posts. Congrats.
I just recently found your blog and have been enjoying your posts quite a bit. I look forward to seeing even more.
Congratulations! Fingers crossed the sleeves straighten out…but until then I’m pretty impressed at how they are slanted in exactly the same shape!
Congratulations on such a long time blogging! You’re not the only one with slanting problems when knitting — this happens to me sometimes too (although I haven’t figured out why it happens or does not happen). Weird. The way you wrote about it literally made me laugh out loud — my dog looked at me, startled. I hope it works out alright after blocking!
Well done on 300 posts and 7 years! Great effort. I’m sure your knitting will be fine after blocking.
This happens to me too. I hadn’t thought it might be because of they way I knit. I also knit continental. Mine usually block out fine.
I believe soknitsome is right. The left side seems a bit looser than the right one. But after blocking it should be fine. 🙂 And congrats to your milestone! Wow, nearly 7 years.
Could it be that it is a single yarn? Sometimes if it is not plied, the fiber is unstable and will result in a crooked fabric.
Wow, that’s some biasing! It’s got to be something to do with the yarn, not with the stitch nor the style you knit in. I guess it’ll be fine after blocking though. Congrats on your 300th post.
As long as you followed the pattern without area you should be fine. They say that animal fibers are very forgiving when blocked. Give it a whirl. Your sweater looks pretty so far.
Congratulations! Your blog is one of my very favorites – thanks so much for taking the time write it.
