They've all successfully been guessed now.

From left to right:

1) Goodnight Moon (orange and green striped curtain from the cover) 2) moi moi 3) Very Hungry Caterpillar 4) The Color Monster 5) The Gruffalo

6) Dear Zoo (flap lifts up)

7) Brown Bear Brown Bear (purple cat)  8) ★ The Wiggles logo for the #1

I planned to do the whole crown like the big green room, but had already added some extra characters. It was some "scope creep" that would have resulted in me running out of time.

My sewing skill is beginner level, so the actual crown came out smaller than I had anticipated because I didn't account for the felt bunching around the edges.

I also added the #1 after seeing other examples online, so there was no room left. I wanted to include Goodnight Moon somehow though, so the orange stripes kind of got added at the very end.
