For the CC I used 27 different leftovers and Tosh Merino Unicorn Tails in an assortment of colors.

All leftovers I used were Merino Singles among them:
Hedgehog Fibers Skinny Singles
La Bien Aimee Merino Singles
Qing Fibers Singles
Tosh Merino Light of Madelinetosh.

Although I love my shawl, I think that this pattern will be even more beautiful with a more well defined yarn that gives a better stitch definition than the merino singles which have the best drape ever.
