Extra Yarn
 

I have tons of yarn that I've collected over the years. A lot of it is left overs without a label. Can I weight those portions on a kitchen scale and rely on that weight to determine how much I have to use for a project?

I don't think so if you don't have labels. I'm not sure how you'd do it I this case. :think: What I do is make something like a scarf or hat that can be made with multiple small amounts.

note to self: always keep the label!

You would need to determine if they're all the same thickness because they have different yards per oz/g. You can use wraps per inch (wpi) to figure out the weight classes, then see how much yardage in each class. This page has a wpi chart at the bottom.

very cool. thank you!

I don't always keep them either.:doh: One thing that helps me tremendously though is Ravelry. Because I put in most of my projects I can look back at what yarn and needle size I used for each. Even if I don't remember the name of the yarn I know that something I made was from it so I can go back and look. This doesn't help you now, but maybe in the future?
