Remember when you had a camera and you take pictures and then you had to get then developed. Oh my how we have changed. WELL many of those pics are out there. I remember when photo places would have specials like 2 for 1. NOW you have all of these photos and in many cases multiple copies.
Stacks of photos can add up and take up space! You don’t have to throw them all out. I have fun and meaningful solution.
Take all duplicate photos out. Your space will increase. Take those duplicate photos and give or send to the appropriate people. Maybe your aunt would love pics of you and her daughter who is no longer with us. Your best friend lost that picture of you and him and your dates at the prom. You can give him a copy. Its meaningful and decreases the clutter in your space. AND its sends positivity into the world.
