I have taken a picture (and many times, several) of EVERY quilt I have ever made. I did not do that with my cross stitch until recently, so a few did get away. I also have a list of who they were made for, and some pictures of the people enjoying their presents. My mother used to take pictures of some of her work and I got the idea from her.
I keep all the pictures and the information in a flash drive that goes everyplace with me. If my house ever burns down while I am away, I will still have that.
