So I just found out about bleaching photos and I'm an addict.  I love it so much.  I've been doing 50/50 water and bleach but the bleach acts so quickly I think I'm going to start doing a little less of it next round.  This is a bleached photo I did for the lid of one of the boxes on my site, www.BoxieLady.com:

This was done with a photo of a disco ball.  I put some stickers on before I put the picture in the bleach solution to spell out "Glow" and to add some stars.
