The Patrick Curved Raglan Shirt from Fishsticks Designs! I'm totally in love, and I would wear this myself if it came in my size. (In fact, I'm thinking of trying to modify a pattern in my size to look like this....)
The curved raglan seams were the only slightly tricky part, but as long as you pin them well and then take the seams slowly, it wasn't a problem at all. I made a 3T for Thing 2 and a 5T for Thing 1. After they try them on, I've got plenty more fabric combinations to make these in!
The red and black interlocks were stash leftovers, as was the orange interlock. The green ants print was a coop buy several years ago. This is the first use. It's a jersey knit, so not terribly thick. We'll see how it holds up. But it's very cute!
