LOL tink, in my endless quest for that Perfect Color, I tend to amass lots of bottles that I use once or twice and then put away, since they are not the Perfect Color!
Every once in a while, when we have family members over, I will go get my plastic shoebox and ask people to do me a favor and please take anything they think they can use.
What they leave goes into yet another box, and when that gets full, I put it in my Blessing Bag, which goes to an organization in my community that helps ladies who are liberating themselves from abusive situations. They are always glad to get clothing, books, whatever you've got, as many times the ladies are starting over from scratch, and have nothing at all.
I like to think that each box will contain what will be the Perfect Color for somebody, maybe more than one!
