Canary’s natural, hand-dyed indigo thread is 100% organic cotton.
It can be used for machine or hand sewing. It’s a sturdy weight, fine enough for a 14 or 16 machine needle. It’s not as heavy as Gutermann topstitch, for example, or chunky like sashiko embroidery thread.
Each colour has its own listing in the drop-down menu under “indigo dyed thread” on the sidebar.
