"Harvest without Birds" is an easy yet so effective cowl pattern in DK weight yarn. Only basic crochet stitches are required, nothing fancy, plus it can worked in any desired width or length - a short neck warmer or a long infinity scarf.
A funky scarf for beginner crocheters, that's "Millepede". The pattern is written for the use of super bulky yarn. However, it will work in other yarn weights as well. Make your own in only a few days!
