I used the horseshoe cable headband pattern from sheilalikestoknit on Etsy. I've never knitted cables before but I felt like a challenge so I decided to give it a go, and I'm glad I did - although the pattern was so easy to follow that it didn't really feel like a challenge in the end!
I used Stylecraft Special Aran in Aster, which was lovely to knit with and is a great colour. The pattern uses two strands of yarn held together which means that the finished result is nice and thick so hopefully will keep my sister nice and warm!
The only problem with making this as a present? I now want one myself because I like this better than the headbands I made for myself in the autumn so it's gone straight back on my to-knit list - it's a good thing this is a quick project!
