The best way to protect your photos is to steer clear of acidic and metal materials. And don’t include excessively lumpy embellishments that could rub against and wear down your photos. It’s also a good idea to ensure your cardstock is acid- and lignin-free. Another piece of advice is to take extra care when handling your photos. The natural oils from your fingers can leave marks that will become unsightly over time. Therefore, always hold photos on their edges and try not to touch the image itself. If you have duplicate photos, it's a good idea to use those instead of the originals.
