I was so excited to start using these towels when they arrived that I unwrapped them and immediately hung them up on the towel racks in my bathroom with out inspecting them. After a day or two I started noticing the brown/tan stains. Since I had already used them there was no way I could send them back. While I'm not that vain to cause a big fuss about a couple imperfections in my bath towels I think that white towels should be just that, bleached white. While house guests have told me that they loved the towels because they are so soft, I think in the back of my mind that I'm just happy they didn't look that closely. I strongly recommend to inspect these towels thoroughly before using them so you still have the option to send them back if you realize they are flawed.
