Each pamphlet has a different set of recommended yarns. The following are from the Loweth version.

Materials
LOWETH Double Knitting
2, 3, 3 20 gram balls
1, 1, 1 100 gram ball
1, 1, 2 50 gram balls.

The Loweth DK yarns shown as published in Ravelry do not include Furtastic or Polka, as they would not be much use for gloves. Crafty Knit is not included either, because it is a 25 gram ball.
