This pattern is a bit difficult with many points where improvisation and experienced interpretation is necessary, but the result is lovely. Mine ended up small, more like 3t than the 4t I was trying for, but it will fit for a little while!
If you are working on this, pay attention when you are making the sleeves. There is probably a way to add an extra set of cables when you start increasing rows. It’s unfortunate that there is a missing set of cables, and if I were doing it again, I would work it in. Hard to explain, but if you are working on it, you will discover what I mean.
I added a row of sc on bottom and sleeve edges. I also did a simple edging to the neck because it looked too plain.
