Paper craft as a physical discipline is ancient — origami, papier-mache, decoupage, and scrapbooking have centuries of tradition across cultures. The idea of bringing paper's tactile qualities to screen emerged alongside skeuomorphism in the early 2010s, when designers still believed digital interfaces should reference physical materials.
Google's Material Design (2014) literalized the metaphor: every UI element was a sheet of "material" with elevation and shadow. But Material Design was clean and systematic. Paper Craft is its folk cousin — messier, warmer, more personal. Where Material Design is an architect's blueprint, Paper Craft is a child's collage.
The aesthetic found its community on Pinterest, Etsy, and craft blogs, where handmade visuals were a natural extension of handmade products. Today it thrives in indie web spaces, educational sites, and anywhere that values the feeling of something made by hand over the polish of something manufactured by committee.
