So, how long do you think it would take to knit a substantial dent in my yarn stash?

As of last night, I'm trying to find out. The plan is to weigh my finished projects on the kitchen scale and keep track of how much yarn I'm actually using and how long it takes me to knit up 5000 grams.

It should be interesting. I'm afraid it might be downright scary to find out how little yarn I use compared to how much I buy.
