When putting together your scrapbook or photo album pages, be aware that the method and materials you use will make a difference in whether your memorabilia will be preserved or damaged. Never use rubber cement, pressure-sensitive tapes such as masking or cellophane tape, staples, or hot glue gun adhesives. Acid-free acrylic adhesives may be used for some materials. Use only a small amount, preferably a drop in each corner. For important documents, memorabilia or original works of art, we recommend using photo corners. Paper corners that are acid- and lignin-free are pre-gummed and can be removed if desired. Clear polypropylene photo corners are self-adhesive and unobtrusive. Use larger corners for items that are 8 x 10” or larger so as not to damage the corners of your item.
