I'm working on the Kai Shirt from Heather Ross' Weekend Sewing. LOVE that book! I still need to add the buttons and hem it, but I'm pretty happy with how it's turned out, despite a few collar complications along the way. This is the 12 month size, and despite the fact that Jack is wearing 12 months on store bought shirts, this is still far from fitting him. My guess is that it will probably fit him closer to when he actually turns one.
