The yarn that needs no introduction. You already love TML (Tosh Merino Light) and you already love tweed, so let's do some combining. Introducing TML + Tweed. This singly ply fingering weight yarn is 420 yards of tweedy goodness. It's 90% superwash merino, 8% viscose, and 2% nylon (for added strength). You can machine wash it cold and dry it flat for your garments and accessories to live long and healthy lives.
