Any individual color-combination of a line of multicolor yarns.
The batch that a ball of yarn was dyed in. Yarns of the same color and the same dye lot will look more similar to each other than yarns of the same color but of different dye lots.
Pull From the Center
Work from the yarn that is coming out the of the middle of the ball. Pulling from the center means the ball of yarn won’t roll around.
Pull From the Outside
Work from the yarn that is coming from the outside of the skein. Pulling from the outside may cause the ball of yarn to roll around.
In knitting, the word “tail” can refer to two things.
1) A tail is any end of yarn sticking out after you finish a project. Tails must be woven in to prevent unraveling. Whenever cutting a piece of yarn, always leave at least a 6-in. (15 cm) tail so that you can weave it in later. This type of tail is also called an “end.”
2) In doing any kind of long-tail cast-on, the tail is the strand of yarn coming from your needle that is not the working yarn.
The official thickness category a yarn falls into. E.g. worsted weight and bulky weight are two standard thicknesses (weights) of yarn. NB: A yarn’s weight in this sense isn’t directly related to its actual physical weight in ounces or grams. That has more to do with the density of the yarn.
The yarn you are knitting with, i.e., the strand of yarn coming from the ball.
