The knitted fabric increases between the two loops of the wire needle, separating them as it increases - magic. You cast off and go twice around and have only one edge - magic. You add a color on one row and suddenly it is all around the whole piece of work - magic.
The fact that I decided to be stupid and did not count the number of stitches - not magic, just normal. It ended up too skinny, anorexic actually, and way too long. Frogged and will start again today.
