I recently finished up the Megan Sweater from Robyn Chachula's Blueprint Crochet. It was made with natural black alpaca yarn from Highland Alpaca. All those names should be familiar to you if you read the blog regularly.
I adjusted the pattern a little because of my large chest but it lies almost the same as the model pictures in the book. I couldn't decide if I liked it better belted or unbelted. Maybe you all can respond and give me a vote.
I always have to adjust sleeves, but I didn't here. I should have gone with my instincts but it was difficult to tell even with trying the sweater on. But the end result is quite fine, too.
