Any adhesive used to mount photos and accessories must be Acid-free. Glue Dots, mounting squares, adhesive foam and liquid glue, and some double stick tape are Acid free and photo safe.

To glue fibers and 3-D elements, try placing liquid glue directly on the paper or where ever you are placing your item, let it sit for a few minutes, before placing the item on the glue. When it starts to dry it will get tacky, place your fibers on top, pressing gently.
