What's that unholy tangle sitting atop the London Review of Books? This is the moment when I thought, "hm, perhaps the famous Russian join is more of a faff than it's worth."
And this is the point where I thought, "hey, actually this is pretty tidy."
And at this juncture, I had decided to make the Russian join my join of choice from now on. It's not just my blurry photography that makes it hard to spot: the join is only discernible as an inch or so of double-thickness yarn, but unlike the method of knitting a few stitches with the new and old ball together, I don't get any irritating tension problems around the join, and best of all, I don't have any ends to weave in.
If you would like to try this magical business, I can't do better than point you to the tutorial provided by The Boy Who Knits, which is the one I learned from. And if you already have this spiffy little trick at your disposal, I am delighted to be joining you in this small paradise of yarn joining.
