This is a pattern for a lightweight, warm for weight blanket, much wider than the bed of the knitting machine.
As described in the pattern, this is knitted in a fluffy mohair. It would work equally well in a fine alpaca fulled after knitting.
The use of Card 7, Tuck, Tension 10, to make a wide, airy textured fabric is the core of the design. It is adaptable to many sizes and purposes
