These mini albums are made from lunch sacks – paper bags. I have made more than I can count and given many as gifts over the years. They are time-consuming to make by hand, but so rewarding when you finish. Mostly they are used as mini photo albumns.
More recently I’ve been using the paper bag mini albums to create wisdom books for friends and family. There are several good tutorials on YouTube, just search for mini albums or paper bag album. I really enjoy Kathy Orta King’s tutorials, so I’ll add a link here.
