Hey Everyone!
A while ago I created an excel spreadsheet to keep track of the sweaters I have knit.
This spreadsheet has three sheets, the first has the sizes broken down by how many of each size I have knit each year. The second sheet has the colors used for each size, and the last sheet I where I am keeping track of how many feet, yards, Miles, ounces and pounds used each year (divided out by sweater size) as well as a grand total of how much yarn I have used. It is a lot of information, but it is nice to have it at my fingertips.
