The mystery item (shown here) is:

A doorstop! I hope you’re not too disappointed. As you can see I’ve added a felt butterfly since. Can’t have something in Little Miss Bossy-Boots’ room that isn’t pink…

I made this one for the door of Little Miss Bossy-Boots’ room as she keeps banging it shut when she’s playing in her room. I don’t mind her closing the door, it’s the banging I object to. Waiting for her to get her little fingers caught or, worse, one of her little friends’ fingers.

She can move a regular door stop but can’t get a hold of this one as it’s on top of the door. Sorted!
