what could it be?

a swimming cap?

a fascinator?

a dinosaur egg?

monika @monicac correctly guessed yesterday's post. it was indeed the bottom of my omelet pan. so far, two of my entries still remain a mystery :-(

This sure is a mysterious one, it seems to have some threads on it. A cloth or pot holder??

[Brigette]

I’ll ask Signorie Weaver

a shell ?

[Maggiemae]

I think it is a penguin licking its lips?

[Kathy A]

I think it’s a shell too but I’m sure I’m wrong

[K1W1]

Great capture of what looks like either a shell or a flower.

[Lou Ann]

You are so good at this challenge! I can’t imagine. Ha!

[Linda Godwin]

close up of part of a sea shell?

[JackieR]

I thought seashell too

[Kathy]

It has a shape similar to a seashell but doubtful it is. I see part of a hand, too, like a thumb and knuckle. But probably not that either. Wracking my brain and coming up with nothing!

[Chris Johnson]

Maybe a figurine of some sort? This is a fun game :D

I don't think it's a swimming cap - because I haven't seen one of those in about 40 years, and I have no idea what a fascinator is. Unlikely a dinosaur egg, because I'm pretty sure you're not that old. So I'm going with a leaf of a lily or some such flower. Or maybe a swimming cap.
