Bookmarks make great presents and can be customized with additional text – for example a photo of Mom and children with "Happy Mothers Day" underneath.
Panoramic photos are an ideal choice for bookmarks. However smaller sized photos can also be used: e.g. a single photo with text below it, or several small photos.
Bookmarks are available in any size, but by default are 2" x 6". They are laminated for durability, but do not have any ribbons etc., to minimize damage to book pages (and eliminate temptation to cats!).
