I have 3 clown Fireflies (hemp). Mostly, a great dipe. The first time ds soaked one of them... the blue dye from the soaker pad bled. It got on other parts of the diaper and stained ds's bum. After a few hot washes, the dipe no longer seems to bleed. Ds's bum was back to normal a couple of days later. I didn't think it was a enough of a problem to return the dipe (I just washed it a few times before I used it again), but I wanted to let Lori know what happened so no other babies would have blue bums. When I called Lori to inform her of the situation, she said they didn't use the dark colors anymore because they tend to bleed. It really bothered me that they knew of the problem and failed to mention it to me, when I purchased it. It wasn't a big deal, and I still would have bought it, but I would have liked to have known ahead of time. Otherwise, the diaper works great, and they're really cute.
ETA: After reading this, I think it came across badly. Lori did offer to let me return the diaper. As I already said, it wasn't that big of a deal, and she was very polite. And, upon further inspection... the card included with the diaper did say to wash SEVERAL times for dark colors. I guess I just didn't think it was a dark color, because only one layer of one flap was dark blue (clown dipe). So, my oops! I really like the FFs, I just wanted to make sure that people wash them enough before they use them. I've bought another one (organic cotton) because I do really like the diaper, and Lori is really good to work with.
