The Oliver + S Nature Walk Pullover in size 3T is a great fit for Isaac now. I finished it at least six months ago, but he just tried it on for the first time this weekend. We didn't do any nature walks this weekend, but it looks nice with our gold tinsel tree.
He is a big fan of the pocket in front. Lots of room for toys.
I remember this pattern being time-intensive. There are a lot of pieces to cut out, and the collar and curved pockets were tricky (for me). I was unsure of it when I finished it - it didn't look great on the hanger, and the fabric seemed stiff - especially on the bottom where it's two layers thick - but it looks really cute on him and he loves it.
