The answer, as with so many things in life is “It depends”.
Sock knitting is often perceived to be hard, for reasons that I’m yet to fully get to grips with. Some people seem to attribute almost mystical levels of skill to turning a heel and the often heard refrain is that ‘sock knitting is hard’.
But really, it’s like so many other things with knitting. A few skills are needed but they aren’t anything that you wouldn’t use on other knitting projects. If you can do the knit stitch in the round then you can knit socks.
Honestly, in my view socks are no more difficult than any other piece of knitting - with the possible exception of a flat garter stitch scarf. Although with socks you are far less likely to die of sheer boredom.
I've known knitters of over 40 years who have yet to knit a sock - and who are too nervous to try. And I've known brand new knitters pick up a set of DPNs or a long circular needle and start knitting socks with complete gusto.
It's more about attitude and willingness to embrace something new than it is about the length of time you've known how to knit and purl.
Like any knitting project, a beginner knitter may need a hand getting started. Any type of cast on can be tricky at first, whether you are knitting flat or in the round. But the majority of sock knitting is just working stocking stitch round and round - totally achievable for a beginner and an absolutely brilliant confidence booster.
The only part that I would say could be a little tricky is when you come to graft the toe closed (with cuff down socks). But the BOB socks shown here have a rounded toe - with absolutely no grafting needed.
If you don’t want to work a heel (although it really isn’t that bad) you could just knit a tube sock.
And at the end of the day, you have nothing to lose. If it all goes pear shaped (and oh - how I wish I’d kept my first sock attempt where the heel mysteriously appeared on the side of the sock rather than in the back) you can just rip the yarn out and try again.
At the very least, it’s more entertaining and you’ll learn far more than you ever will slogging away on a 6-foot garter stitch scarf.
If you'd like to know more, I've put together a blog post with some resources and suggestions for the adventurous sock knitter to be.
