Gray yellow zig zag

I have started a new project. My mom wants this project. I asked her. I have never worked with Gray before so this is coming out really pretty. More than I expected.

Bright yellow and heather gray. It looks much better in person than camera.
Chained 210
Working in the back loops. Single crochet 9, three in 10, then single crochet 9, skip 2, single crochet 9, three in 10. repeat all the way across.
Pretty simple. I did 10 lines of each color.
