Since I figured her two year old didn't need a hundred Pj Pants, I'd make a little Backpack out of the train fabric. I didn't feel like making a front pocket for this one, mostly because I haven't liked how they've turned out in the past. So I stayed pretty simple with the design. The backpack might be a little big on a two year old, but at least it's not too small. I paid my kindergartner to model it for me to see the size on him.
The inside is a robot/ train fabric.
I think the straps are a little long and I didn't end up making them adjustable. I'm awfully excited about how cute it is. I just hope it fits him and is functional as well.
