The thing I found with this pattern was that it called for a foundation chain of 40 stitches, but I needed to use 45 even though I was using the recommended 6.5mm hook. I used a worsted yarn, so maybe if you're using a chunkier yarn you'll be okay with the 40 stitches. But, just play around if not.
I had to learn how to front post double crochet, which is soo easy. And I love the look it lends to this ear warmer. I'm thinking this might very well turn into a favourite stitch for me ♥ Since I had no idea how to front double crochet, a stitch I had tried before but hadn't had much success at (I'm thinking now I was misunderstanding the written directions I was referring to at the time) so I decided to Youtube. And I found a video that made it super easy so I am sharing that with you!
I hope you'll try this pattern, if only because it's practical and so much fun! Or just to practice the front post double crochet if it's new to you.
