Ammonite Fossil Coaster Pattern!

Finally got the pattern to a nice state, so I'm posting it as promised! This pattern should be easy for anyone with an understanding of double crochet and upwards types of stitches! Feel free to use, and if you really really like it you can drop a few buckaroons in my kofi here, but again this is free! I don't feel comfortable charging money for any patterns I make, at least not yet lol.

I even learned how to make a cute fancy pdf for it!

Flynn likes to be involved with everything I do. If he sees me crouch down to look at something &/or pick it up, he likes to come & inspect it as well. In case it's interesting. Or edible. Or both.

In this case, I'd found a fossil. According to Flynn this falls in the "Not Interesting" category but he gave it a polite sniff all the same. Like I politely praise him when he finds & shows me puddles & molehills. We humour each other.

Such a teeny tiny fossil! It's one of the smallest I've found. Probably at least 420 million years old, which is just completely wild.
