I am currently swatching for a new pattern, which is due for publication in autumn 2014, with Araucania Botany Lace.
Sometimes, I just don't want to follow a pattern. So, I create my own. Not least because I secretly enjoy going through the hardship of counting stitches, knitting swatches, changing needles and knitting more swatches. Just for the sake of it.
Apparently, Araucania Yarns are ethically sourced, at least this is what it says on their Facebok page. Apart from an entry on facebook, I couldn't find an active page when searching for the manufacturer's website (presumably: http://www.araucaniayarns.com/ ), but I wasn't searching too hard.
