If you want more information about it, here's a review including a comparison with Eucalan in a washing test on Knitter's Review. In the review the author mentions the strong smell of the tea tree oil, but that might be a bit during the washing of the garment, but afterwards I didn't smell anything, nada, niente.
I'm going to cheat a bit and call this capelet a finished project although it is only sort of finished. I think I could wear it now (well, it needs a bit more blocking to keep the bottom edges from curling), but I'd still like to add one or two more pattern repeats (someday :D)
Yarn: Karabella Aurora 8, 100% extrafine merino wool, 90 m/50 g, 98 yds/1.75 oz
Color: #32 Light Pink
Price: $4.99 (I was lucky and it was on sale at www.sandrasingh.com)
Amount: 4 balls (I had to frog one swatch, because I did not want to start a new ball for the last row of the ribbing part)
Needles: 5 mm
Gauge: two pattern repeats = 12 cm, 24 rows = 10 cm
Dimensions: 49 cm wide at the bottom, 40 cm wide at the top, 30 cm long
I would not really call the color "light pink", more like "peach" or "salmon". As you can see this yarn is fabulous for cables and for patterns with a lot of structure. It's a thick yarn that after washing becomes very soft and velvety, but still keeps its plastic structure.
And I have to repeat it once more, I really like this book. Usually I just don't like ponchos, but there are some in the book that look really cute. The capelets and wraps are also very nice. Buy it. :D
