2. Demonstrate the following:
a. Cast on
b. Bind off
c. Cable stitch
d. Ribbing
e. Garter stitch
f. Stockinette stitch
g. Pick up a dropped stitch
3. Know how to care for these kinds of yarn:
a. Wool
Wool is sensitive to agitation and hot water, which causes the overlapping scales of the fiber to stick together, what we call shrinking, or, if we do it on purpose, felting.
To avoid this, wools should be washed in lukewarm water with little agitation. Most people prefer to wash wool items by hand to avoid any possibility of felting when they can't see what's happening inside their washing machine.
b. Hair
c. Synthetic
Synthetics are well-suited for the many currently popular novelty yarns, and their range is vast. Manufacturers continually attempt to make synthetic yarns that mimic the best properties of the natural fibers. Synthetics are generally durable, water-resistant, and strong, but can also be somewhat non-breathable and non-insulating. Most are machine washable, but are very sensitive to heat, and they will melt or burn at fairly low temperatures. Nevertheless, knitters can’t help but be drawn to their seductive textures and rich colors.
Polyester: Polyester is made from a group of condensation polymers. It is resilient, smooth, crisp, and springy. It can be shaped with heat and is insensitive to moisture. It is lightweight, strong, and resistant to creasing, shrinking, and stretching. It is nicely washable, and is not damaged by sunlight, weather, moths, or mildew. Polyester is very often combined with other fibers.
Acrylic: Acrylic is a synthetic polymer fabric or yarn, and is lightweight and warm with a very wool-like feel. Although it is resistant to moths, oils, and chemicals, it is prone to static and pilling. 100% acrylic yarns can be a bit “cheap-looking,” if not chosen with care.
Nylon: Nylon was the first completely synthetic fiber. It is strong and resistant to many chemicals and moths. It is also easy to wash and is very non-absorbent. It can be a bit scratchy if not blended with another fiber.
Viscose / Rayon: Viscose is a man-made fiber made of wood or cotton cellulose treated with sodium hydroxide to make a liquid that can be extruded as cellophane or rayon yarn. Rayon fiber is quite absorbent, dyes very well, is soft, and has a nice drape. Although it may shrink, it does not melt at high temperatures, and it is resistant to moths, bleach, and many common household chemicals. Rayon thread is divisible, shiny, and good for blending, but is not hard wearing.
