Friday egg today is a kind of egg that I don't think I have ever shown here: a rhea egg. It's smaller than an ostrich but about twice as big as a goose egg and comes from a prehistoric looking bird (similar to an ostrich) that is native to South America. The egg has smaller pores than an ostrich egg, but they are still visible in the close-up photos. I like the extra texture they add to a design.
I've been circling circles for a few weeks now, so you will be seeing more of them in the coming weeks.
