My cave seems to have a bigger window than the photo in the pattern, and the ‘roof’ isn’t as neat. I think in future I would work in spirals rather than joining each round. This is the smallest size, with a 3″ diameter base.
One more for Wildlife Rescue Nests.

So cute and whatever critter (I am hoping this is for your nest project) gets this will be so lucky!
Yes, this is for Wildlife Rescue Nests. Thank you for your comment.
I’ve done a few nests and a cave. My cave seems to have a big opening too. Will get them photographed thus weekend.
