YARN: Any aran weight yarn. I used Léttlopi by Ístex yarn:
#9418 Stone Blue (22 g / 48 yd),
#0051 White (30 g / 66 yd),
#1700 Air Blue (10 g / 22 yd),
#0005 Black Heather (10 g / 22 yd),
#1703 Mimosa (4 g / 9 yd).

The yarn consumption is approximate—you will probably need less. You may also need 5 stitch markers.
