As you can see, I have the bottom two squares completely filled in. It's a lot of confetti but I've been working one color at a time over the course of a square and then parking the thread.
The only issue I have is that I don't really know where in the picture I am. I know I'm somewhere in the middle. I think I'm stitching a tree but I'm not quite sure. Eh, it will become a little clearer while I stitch.
