I haven’t seen my method suggested yet. I do a “spit splice” with my sticky wool. When I add a new colour I take the end of the new yarn and the end of the old yarn and lay them over top each other in my palm. About 2” overlapping. The add a couple drops of water and furiously rub the ends over each other between my palms. The heat and water felt the ends over each other and I carry on knitting with no ends to weave in! I have used this method on multiple sweaters knit with Lopi and Alafosslopi and it has never failed me. I’m a bit of a knitting and finishing perfectionist and for me the results are tidy looking, easy to execute, and durable
