If you aren't ready for the commitment of a full-on sock yarn blanket, scrappy socks can be a fabulous way to use up all those odds and ends. There is a wonderful hashtag on Instagram called #frankensocks and this is well worth a look for inspiration. Totally mismatched, fun and colourful these type of socks look amazing and are totally unique.
If, like me , your brain can't deal with totally random socks you could always strike a happy medium by knitting striped socks in brightly contrasting colours. I knit a pair recently, using them as an opportunity to showcase a range of sock yarn leftovers in my stash from some of the very talented indie dyers we have here in the UK. To make sure that the socks matched - there's my inner control freak talking - I knit them toe-up, two at a time on a long magic loop needle. This did involve a bit of extra faffing as I had to wind off enough yarn for 2 balls, but with each stripe/ball only taking 3-4g this wasn't particularly onerus.
In fact, just between me and you, it sometimes took me longer to decide on the next yarn stripe than it did to wind it and knit it.
Taking the #franskensocks theme a step further there are some very popular advent themed scrappy socks projects out there too. The Opal Sock Yarn Advent calendar is a very popular one which is almost certainly sold out by the time you read this as the kits went on sale around the beginning of October. Many thrifty-minded knitters however have decided to do their own advent socks - knitting a stripe each day on their socks - ending with a snazzy new pair of socks ready to wear on Christmas Day. Some have even gone the whole hog and have their set of little yarn balls all ready to go in individual sealed bags. With all the hectic preparations going on before the holidays, there is something very pleasing and soothing about making time to sit down each day and knock out out a stripe or two on your fun, colourful project.
