My sister finally has her sweater! I didn't get to give it to her in person. I sent it home with her husband when he came to pick up the girls yesterday.
The verdict is good! It fits, she loves it and thinks it will be an excellent addition to her wardrobe. This is good news because my sister is a bit particular about her clothes and I wanted to make sure I made her something that she'd get some use out of. Also, she promised to wear it to Thanksgiving so I can take pictures.
That success under my belt, I've got the next sweater all lined up!
