So close to finished!
After finishing the stitching on the cats (yay!) I wet-blocked them to get rid of some of the wibbly bits where the stitching had distorted the ground fabric. I washed the piece with Soak no-rinse wash and then rolled it in a towel to get rid of excess moisture. Then, I pinned the heck out of it, making sure that it fit the dimensions of the pillow form (18″ by 18″) and that the edges were more or less straight.
