One of the first crochet projects I did several years ago was this Southwestern Ripples Afghan.
The pattern was from the “I Taught Myself to Crochet” booklet by Boye using Boye crochet hook size I and worsted weight yarn in 4 colors: 24 oz. cream, 8 oz. tan, 8 oz cinnamon, and 31/2 oz. black.
I’ve seen this pattern everywhere even on TV shows in the most unusual color schemes. Simple.
