Lyrical is a kind of contemporary dance that is used to describe dance that has more of a connected and continuous movement pattern (ie soft, gentle): and some other term probably exists to take over the dramatic, contrasting, sharp movement style that can also exist under the umbrella of contemporary.
Hard hat sizes can seem a bit mysterious. To measure for your hat size, place a soft cloth tape measure around the widest part of your head (this is usually just above the eyebrows). Pull the tape measure snug, but not tight. Convert inches to hat size using the sizing chart below.
Once the crown of your hat is big enough you knit straight stockinette stitch, so without increases, for about 4 inches. Knit one inch only of ribbing if you want a simple hat. Knit 3 inches or more if you would like a folded brim. Once you have finished casting off take your end and your yarn needle.
