Hi guys!
I'm new to the forum. (Well, I've been creeping quietly for a while)
I'm getting a hatchling spider ball python later this fall!

Approximately what size hide is comfy for a hatchling ball?

[I'm making them out of waterproof oven-bake clay, because it's fun and they look snazzy]

I just don't want to make it way too big or way too small. Though I suppose I could always pack it with moss or something if it was too big.

And how big should the entrance be for a little hatchling head?

Thanks!
