Ways of keeping track of knitting

[lissaplus2]

I got this widget thingy...not really sure how it works yet but im supposed to put in how many yards i knit a day and it keeps track for me... I may be shocked as to how much i really do knit. I mean, i know i knit alot but it will be interesting to see how much. If I can figure out how to keep track of how many yards? It would be great to find something similar that I could just put in total yardage of project and then tell it when Im done. Oh well I may just do that with this thing.

You can do it by weight if you have a postal or baking scale. Grams are easier to work with than ounces. So weight the skein(s) before beginning and then after you're through for the day and subtract the 2nd from the first. Let's say it's 20 grams. Go back to the label and divide the number of yards in the skein by the number of grams. That will give you how many yards per gram-- let's say it's sock yarn, 200 yards for 50 grams. Every gram would be 4 yards. So 20 grams times 4 yards would mean you'd knitted 80 yards that day.
