One must have some knowledge on how to make the plaid. I do give a link to a youtube video, as it’s better to visualize this technique and how to make the colour changes. This pattern uses the front and back post double crochet for the ribbing cuff, and some other simple crochet stitches. It is done using worsted weight yarn # 4. If you have any questions, please do not hesitate to contact me. Thank you for your purchase and Enjoy :)
