Sonnet is Finished

I finished Sonnet on Thursday morning and wore it to work. The only problem is how stretchy the neck is. The shoulders keep slipping down. I will need to do something to tighten things up. Suggestions include grosgrain ribbon or crocheting the edge. Since I have never crocheted anything, I'm a bit anxious about that solution. The sweater looks good and I'm afraid of messing it up. I've decided to stew a bit about it and address it some time next week.
