This pattern doesn’t go to a size 3. I added 12 stitches to the body and one inch in length. I added
3 stitches to the sleeves and also one inch in length. It seems to work out well.
The pattern is fun to do, although I didn’t like the yarn I used. It’s soft, but plasticy feeling and wasn’t easy to knit with. Also if you had to take out, it didn’t hold up well.
