I was hugely influenced by Sandra Juto's Wrist Worms, when deciding to try and find a pattern on the internet to crochet some myself. I had already bought two pairs of arm warmers in the ASOS sale at the end of last winter, so was sure that they would be easy enough to make.
I managed to find a 'Beginner' pattern and used some Aran yarn that I already had, which I used with a 6mm Brittany hook. I'm very pleased with the outcome. I'm thinking it would be a nice touch to crochet three little buttons to run up the side of each arm but I haven't got around to that yet. Also, I'm interested to see how they will turn out by using a different yarn, hook and stitch.
