Pitanga Yarns has a lot of great products
My go to for crochet in Canada is Pitanga, they carry Cascade Ultra Pima in DK and fine. I would love to see a larger selection of natural only yarns, as that is definitely the way the crochet community is going ! Hemp, Cotton and Bamboo, and their blends are really bursting onto the market and I am waiting to see them at this amazing store.
