I buy Color Catchers at Walmart

If you can't find them, you can make your own. I have not tried this, just ran across it.

I know I am late but if you go to Pinterest.com there is a recipe for how to make your own. I know how Canada can be as they don't always have the same products in your Wal mart that we do.
