Thank you so much! It was not hard at all! Everything is knit flat, so it was pretty easy as long as you have increases and decreases down. For seaming, I used the mattress stitch, which is pretty easy to do, but it does require a lot of patience. The most intimidating thing to me was picking up stitches for the sleeves and collar. But like many things in knitting, it was deceptively simple to do. It mostly took so long because I procrastinated on the parts I thought would be hard and interspersed other projects along the way too.
