Looking for a pattern

I started this scarf several years ago, ran out of yarn, lost stitches, found the right yarn, and now I can’t find my pattern. I know it is a variation of the shale pattern, but I’m not nearly good enough to recreate it. Help please

Welcome to KH!
It’s great to pick up this lovely scarf and finish it. I’m glad you could find the yarn.

This pattern is actually the authentic feather and fan. The old shale pattern is mis-identified as feather and fan. This article explains it and gives a pattern for each. Try it out with some scrap yarn and see if you can get the same look as your scarf.
