When choosing a beginner-friendly pattern, look for rectangle scarf patterns that use simple knitting stitches like garter and stockinette. These are great for beginners because they only involve knit and purl stitches. Avoid complicated designs that involve lots of stitch and yarn color changes. Also, choose patterns that use thicker yarn, such as jumbo or super bulky yarn, because it creates larger stitches and makes the project quick to complete.
