I couldn't do what you do, Vicki. I don't like to handle the pads while I'm working because the ink gets on my fingers and then all over anything else I touch. So I have nine blender tools, which means I can set up for up to that many colors and not have to fool with the pads once I start working.
Keeping them in little plastic baggies is working for me pretty well, once I found the kind that have a white space on them where I can write in the color names. I'm going to stick with it for now. I am now just keeping them lined up in a plastic container. It helped a lot when I finally got my Distress Ink storage unit from Organize More. Having the pads stacked up on top of each other was a big nuisance. Now I can just pull out the ones I want.
