From the publisher:

“Combine tiny cap sleeves, to-days fashion darlings of slender teenagers with this soft-as-a-kitten angora and you have a delicious party jumper. We made ours with a cunning arrangement of colour, graduating from dark to light (incidentally a wizard waist-line optical illusion), but if you want to use up scraps of old wool, you make it in variegated stripes-- or even all the one color, we don’t mind at all. The pattern is the easiest thing in the world to follow for the Striped Angora Jumper.”

Pattern calls for:
1 oz 3-ply crochet wool
3 balls “Fuzzy Wuzzy” angora in a light color
2 balls dark toning color angora

One pair each No. 12 (US 2), and No. 10 (US 3) needles.
4 double pointed No. 13 (US 1) needles
5 small buttons

Notes:
The original was made in five shades of the same colour from light to dark angora to tone. As only small quantities--sufficient to knit 20, 16 and 12 rows respectively--are required for four of the colours forming stripes, scraps of crochet wool may be used. But remember that one complete skein of crochet wool for ribbing and colour at the base of jumper, and four complete balls of angora are required.

Throughout the directions, colours are referred to simply as A, B, C, D and E, working from darkest to lightest toning.
