This design was even easier than the Bettna cardigan!
This side-to-side was knit in 5 pieces. The two lower fronts, the lower back, seen below, unblocked:
and the two sleeve/upper fronts, seen below (unblocked)!
Here are the 5 pieces, just laid out for a trial! The sleeve/upper body
pieces are folded over lengthwise, as you can see.
