You can do it, Pam!
I was not that careful with the seaming at the shoulders, because I was in a hurry to get it done, and it looks just fine! I made mine an inch shorter than the directions specified, because I'm a short person (5' 3"). I didn't want it to hang too long, and make me look like a little girl.
The thing that really dresses it up, and makes it look finished is the buttons on the side. Makes all the difference in the world.
I found my buttons at Hobby Lobby on clearance! Yay! They are nice, big, wooden buttons too. I also got a big, pretty green button to put at the spot where the neckline separates, just to give it some strength at that spot. It makes it look good too.
I put it on last night, and walked down the hall to show it to my hubby. He dropped open his mouth, and said, "Wow! That looks GREAT!"
Gotta love a hubby that compliments knitting projects.
Here are some photos I took last night:
