This pattern by Ashley Knowlton is available as a free Ravelry download here.
It is a well-written pattern that has taught me a new technique (drum roll) : the Vikkel Braid! This is an easy stitch with a great, and dare I say, a rather spectacular outcome. In any case I love it and am chuffed with the mitts, which are perfect for gift-knitting.
I used The Fibre Co Terra , an alpaca, silk and wool blend (aran weight). The yarn is discontinued, which is a shame, because it is very soft, and has some nice tweedy speckles and unusual colours.
