When I tried this yarn, it was love at first stitch. Extra is a durable blend of baby alpaca and merino wool. It's soft with a springy twist and has excellent stitch definition. It also holds up to lots of wear and tear, and even ripping out and reworking, without pilling. I know because my last design was ripped back numerous times and the yarn looked like it has just come off the skein. Each 150 gram skein is 55% baby alpaca, 45% merino wool, approximately 218 yards/199 meters, and has a suggested gauge of 4-5 stitches per inch. Hand wash or dry clean.
