With what we call a "kangaroo pocket" on the front. (I'm not sure, but I might have gotten carried away a little with the decoration.)
For some reason, although (or because?) I took more time and care with this than with my daughter's shirt, it went together quite wonky - the sleeves didn't fit right, the neck is a bit tight, the seams are a bit crooked.
Oh well. He likes it and wears it. (Yes, I know Easter is over. I'm not sure he does, though. DD and DS sang Christmas songs well into February.)
The fabric's a wonderful cotton jersey, thick and stretchy and colorful, called "Campan jersey" by the fabric brand Hilco. The borders, as usual, by Farbenmix. No pattern, just copied and altered one of his RTW shirts. Made the pocket big enough for his favorite soft toy!
