Swirls

The Swirl uses the combination of mosaic knitting and decreases&increases that allows to knit those wonderfully rounded lines. I think I really pioneered that technique. Just like all mosaic patterns, this one is quite simple. But because there's something else added to it, you need to be paying attention. The most important thing when knitting those type of patterns is to remember where the wrong and right sides of your knitting are, and to keep all yarnfloats on the wrong side. I am no kidding. If you can do that, then you can knit it. Definitely much easier than brioche; some people asked about it.
If you are curious about other patterns with this technique, you can check my Peacock Challenge out (that one is probably more difficult, because I charted it),  Leaves shawl, Beren, Princess Peacock (use sport-weight, not fingering for that shawl), to name a few...
