Casted on for size 2-3T with 5.0mm needle, gauge 16sts before blocking, after 14sts.
Used ‘double sead stitch’ on collar and edges. Made decreases on all the sts (not the sead stitch edge) on the last row on RS before the sead stitch edge like this:
K1, K2tog. I’m so pleased with that decision. It made the coat not so floppy.
On the arms I made one more decrease than pattern said.
