According to the website, there are two types of yarn available:
Harvest is a one of a kind blend of Black Welsh Mountain black fibre and white Suffolk fibre. The result is a beautiful, naturally heathered, steely grey 2-ply yarn that is perfect for your next worsted/aran weight project.
Heirloom is a lovely 1-ply yarn and is naturally dark black from Black Welsh Mountain sheep. A fingering weight yarn, perfect for intricate colourwork, or a beautiful lace shawl!
You can find the yarns and some kits at the Alberta Yarn Project website, though they do show up at fibre events around the province and hold Craft and Draught events in Edmonton.
As much as I like bright colours and striking dye patterns, natural yarns are so appealing because they remind you of the animal that gave its fibre to keep you warm. I think Canada and Alberta, in particular, have something unique to offer the world of knitting and fibre, and so this is such a cool project and offers a great way to try out Albertan yarns.
