wpi = wraps per inch. Begin by wrapping the yarn around the ruler. Don't wrap too tightly. The goal is to get the yarn strands as close as possible without overlapping them or leaving holes. Once you've wrapped your yarn, count the number of times you wrapped it around the ruler within the first inch. That is your wpi.
ply = in English for the thickness of the wool and in American English for the number of threads.
I´m always thrilled buying new wool - what happens pretty often to my husbands regret. I just can´t stand back. In most of the times I directly do a gauge according to the recommendations on the wool or the pattern - in case I really managed to buy the wool because I needed it and not because I liked the colour.... Sometimes there is a bit of a time in between doing the gauge and starting with a project and I simply did forgot with which needle size I knitted the little piece of garment. Now I make a little tag with needle size, stitches and rows to fit the 10cm and attach it to the gauge. I take the tags of Avery Zweckform. Nice wool needs nice frills. Or you just take a piece of paper, punch it and attach it to the gauge with a little thread.
