I need help with dye lots in a crotchet project.?

There is white and then there is white! Believe it or not, not all white is the same! Use a couple different dye lots in a project and you will see immediately the difference. Get all that you need, plus a bit more. Some shops will allow you to bring back any unused spools of yarn. Ask first when buying if you can return what is left over. Or you may find someone on ravelry that will need just a little bit more of your lot... that is a good way to share your resources.
