Tulla Tweed is a machine-washable blend of fibers featuring merino wool and recycled cotton yarn, featuring a self-striping blend of colors and a tasteful tweed fleck! It is absolutely gorgeous knit up.

It is a chainette construction which creates garments that are lightweight, less likely to pill, and exceedingly warm as heat is trapped inside the hollow core. 

Note that chainette yarn is typically worked up on a larger hook/needle than you would use with a plied yarn — be sure to swatch!
