As scrapbookers we know this but please pass this onto the people you know. DO NOT USE SCOTCH TAPE ON PHOTOGRAPHS!!! I have spent 7 days 6 hours each day going through all of our family pictures organizing them, placing them on 12 x 12 acid free paper, and labeling each picture with names. There are so many pictures that have been ruined by placing scotch tape to hold the picture to the paper. Some of these pictures go back to the early 1900's. I also cannot tell you how many colored pictures were ruined because they were not properly mounted on acid free paper.
I am just relieved I finally finished this project. The stack of albums was almost as tall as me.
A few years ago I did a huge family scrapbook so I was extremely lucky that I sat down with my mom to identify all the people. My mom and dad died recently and all of that history would have been lost if I had not taken the time to sit with her.
Dont be afraid to throw pictures away. I tossed so many pictures of thumbs, dark pictures you cannot make out the scene, and some that were "exactly what were you trying to take a picture of?"
