Accordian book
Made this today. It’s pocket sized, roughly 3″x4″, and could hold lots of cheat sheets … or whatever…

Made of patterened and colored scrapbooking cardstock. One tag sticker with hole pre-punched and yarn bow.

Four accordian packets affixed to the colored cardstock.

The accordian sections have six folds which show as thirteen sides and one side attached to the green.
