Or, you could sew a bunch of different shorter colored strips together then cut them. It would be scrappy, yet quicker.

I did my avatar that way! I do something
New with each quilt so I can keep learning
And pulling my hair out!!

I've done several. I find it helps the pattern show better if you choose a solid color like off white opposite the chain pieces. Or, use a solid for the chain & scraps for the background. Either way it looks awesome.
