I use this in stranded colourwork to increase and it is absolutely phenomenal, it looks perfect. I used it for the gussets in Eunny's Endpaper Mitts and Anemoi mittens and it looks perfectly smooth and flat exactly like the rest of the knitting. I was amazed! It's like the motif was in fabric and cut out, no bumps along that edge... although I mirrored the direction of the yo at first, and the side where I did them in the same direction as a normal wrap or yo was not so smooth, I could definitely see the difference on that side. So for that inc in colourwork I now do them in the opposite direction.
