My nephew just had his first birthday. I wanted to make him something to wear, like I've done for his sister for each of her birthdays. I chose the Oliver + S sketchbook shirt. I made the 12-18 months size and it fit him - I hear he's already worn it twice!
The only modification I made to the pattern was to use snaps instead of buttons. I figured that snaps are easier for me to put in than buttons and buttonholes, and are also easier for his parents to fasten and unfasten when they're dressing him.
I felt like a sewing rockstar when I put in the collar - I followed the instructions in the pattern, including hand basting the collar to the shirt rather than pinning, and it went very smoothly. Next time, I will use Nicole's trick of cutting the interfacing for the collar to make it fold more nicely. I also love the little box pleat in the back.
I think I will be making this one again as my nephew gets bigger. And it was a great way to dip my feet into shirt sewing. I plan to work my way up to shirtdresses and men's and women's dress shirts!
