What is Gauge?
Guage is the number of needles used per inch.
The lower the gauge, the more loosely knit the sweater is.
The higher the gauge, the more tightly knit the sweater is.
The twisting process helps to form yarn much like braiding your hair.
2-ply yarn consists of two strands twisted in opposite directions and then twisted together to create resistance.
By using 2-ply yarn, your jumper will hang straight and luxuriously.
A sweater made with a single ply only has motion only in one direction and this can cause your jumper to warp and hang rather badly.
Also, the thicker the ply, the heavier and warmer your jumper becomes.
