From the Quince & Co website:

Ibis is a big sister to our laceweight Piper. A 2-ply bulky weight comprised of the same Texas-sourced 50% super kid mohair, 50% superfine merino content, Ibis boasts the same gorgeous halo, sheen, and silky softness, in a luscious heavier weight that’s quick to knit and super warm. Perfect for accessories and sweaters that are meant to keep the cold at bay. For ample warmth and a luxurious fabric that needs to be worn to be believed, we recommend a gauge of 2.5–2.75 stitches per inch on size US 11 (8 mm) to US 13 (9 mm).

How to care for our wool and wool blends:
We recommend that you hand wash your wool project with gentle soap, such as Twig & Horn’s lanolizing Wool Soap, in cool water. If using a gentle soap such as Wool Soap, you do not have to rinse. If you use a regular detergent, rinse it thoroughly and gently press out extra water and roll it lightly in a terry towel to absorb more of the moisture. Lay your project out to the correct measurements and let it dry naturally. If you want to speed up drying, aim a fan at the drying surface.

If you’d like to try machine washing your wool and wool-blend garments (not recommended), use cool water and a gentle cycle. After spinning, lay your garment flat to dry. And never, never put your knitted wool garment in the dryer.
