In 2014, my friend Tamara from Moogly Blog began hosting year long afghan crochet alongs. Over the coarse of each year, she shares 24, 12" crochet square patterns designed by guest designers and then wraps up each afghan crochet along with instructions for a border. If you were to dedicate a couple hours of crochet time each month, by the end of the year you'll have a beautiful afghan! The Diagonal Chevrons 12" Afghan Square was designed to be afghan block #4 in the 2021 Moogly Afghan CAL. You can find the free crochet pattern for the 12" afghan square in this post below, or an ad-free print friendly version on Love Crafts here, Ravelry here, or on Etsy here.

This is my forth year designing a 12" crochet afghan square for the blanket crochet along over at MooglyBlog.com. I previously designed the Cabled Blooms 12" Afghan Square here, Textured Twist 12" Afghan Square here, and Triple Textures 12" Afghan Square here. I love following along with this afghan crochet along and watching everyone's different color choices produce so many unique afghans.
