I was watching the Miss Fishers Murder Mysteries on Acorn T and winding a ball of yarn when I came to a broken end. Ordinarily this would upset me but today I thought it gave me a chance to try out spit-splicing for the first time. I couldn't find the end the yarn broke from, so I rewound it from the other end, to find another broken end about a yard from the end I knew was there. This was a little trickier than the video I found because the yarn was 4-ply. I managed to interchange them quite well. I dampened the strands with water, rubbed them vigorously between my hands, and like magic the yarn felted to a strong union. I think this will revolutionize my knitting.
I used my cell phone camera. It isn't as easy to use as a regular camera. I must remember not to chop off the cat's ears.
Here's Christy Nelsons's video I found on YouTube that showed me very well how to spit-splice:
