The yarn stash

Choose from hundreds of yarn colors before casting on

We photograph each yarn in our studio using consistent, professional lighting to capture its natural texture and color variations as you would see in outdoor daylight.

We then calibrate each yarn photo against a reference target to more accurately visualize what the colors in your finished project will look like.
