7 yards of lilac scrap yarn (acrylic, not sure what brand), plus an unknown amount of white Bernat Softee Baby yarn (also acrylic).
No pattern really, just 6 or so rows of K1P1 rib, then switching to the white for some stockinette. When I was nearly finished with the decreases at the crown, I switched back to the lilac. Just in time, as it turned out, as I had about 6 inches left after the bindoff.
