How do I crochet this stitch pattern? Thanks for any help

How can I crochet this stitch pattern? Can someone explain how it’s done? Thank you so much

Hello Cordula, welcome to our forum. Did you ask the source of the image—that is, where you found this image? You’re not allowed to upload images here that aren’t yours. I’ll remove this image sometime tomorrow during the day. If you’re lucky, someone here in the forum will be able to help you by then. 

Good morning, that’s going to be tricky. 

Have you tried searching online for “crochet shell pattern”? I found quite a few there. Maybe your pattern is among them

I wish you the best of luck

Thank you so much for the input

Hi, to me it looked like several front post double crochets that are worked together.

Best regards, Sabine
