Yaya is the Quechuan word for "greatest,” and this super bulky weight yarn deserves the title. Yaya yarn by Mirasol is a single-ply, 100% superwash Merino wool yarn that is large and in charge for super-fast last-minute gifts, but also so, so soft. Available in hanks of 3.5 ounces (100 grams) and 54 yards (4.6 meters).
