|The fabric is printed with jacks.|
I added buttons to the back instead of a zipper. It was way easier than I thought. I sewed on the buttons with the machine too, which was fabulous. You just put the stitch length to 0, and slowly hand crank the needle to figure out how much it should zig zag. For these little buttons a 4 worked out. This page has a ton of great button/buttonhole information.
Oh yeah, the pattern is Simplicity 4243 Babies. This is the 12 month size and she's about 19 pounds here. It's roomy in the chest and arms and will fit her for a while.
