I recently found a fun, new pattern for crochet earwarmers!
It is a fairly simple pattern that works up quickly. I think the pattern should be considered advanced beginner or intermediate level. The only thing I did differently was omit a few rows since it was a little loose around my head. You can use any standard medium weight yarn. Acrylic is warm, but the cheaper yarns can be scratchy. Cotton is usually not scratchy, but it is not as warm. I used Red Heart Soft yarn – it is 100% acrylic but is not scratchy at all. These make great stocking stuffers, and they are perfect for the cold weather!
