The Yarn Calculator Shop

Fine yarn & heirloom tools, chosen by makers.

Hand-picked from Furls, McIntosh, Rowan, Jimmy Beans Wool, Knit Picks and Herrschners. Every pick has a reason, and every yarn lists the weight, yardage and fiber you need to plan it with our calculators.

Houses in the shop

How the shop works. We don't sell anything ourselves. Every product links to the shop that sells it, and we earn a commission on purchases through those links, at no extra cost to you. It's how the calculators stay free.
