Here's a detailed view of the peek a boo slit in the center of the front and back.
I've completed the bed skirt that matched my simply modern baby bumper. We currently have the crib set up as a toddler bed, so I can't get the full effect of how it looks. Here's a picture of it hanging on the ironing board. I'm very happy with the way it turned out. My measurements slightly off for the front and back, but no biggie.
Now I'm working on the decorative pillow. It's yellow with white mitered border and trimmed with brown piping. Since it will be inside the crib, I didn't want to add the graphic circle print on the pillow. I think that will be too busy.
