What I wasn't expecting to spend so much time on was the buttons. But it took three tries- sewn on & carefully clipped off- until I found buttons that I liked. 

I added the yellow for a dash of color, in a gender-neutral kind of way. Yellow and grey go with just about anything, right? 

Speaking of little guys, I want to cast on a vest for mine next. I'm thinking about casting on a 3T size to accommodate for growth, and his Glorious belly. I'm learning that the rolls and roundness go away much too quickly, so I'm enjoying them while they last!
