According to the Artsy Craftsy, a Junk Journal is "a handmade book made up of recycled items such as papers from magazines, brochures, patterned paper, music sheets, envelopes, packaging, brown paper bags, maps, greeting cards, post cards, doilies, to name a few. The book covers can be made from cereal boxes, old book covers or any hard card boards. The list is endless, especially when your creative imagination is sparked!"
