Makeful Challenge: Cellphone Cases

Collaged Geometric Case

For my case, I used a series of triangles cut from an assortment of paper to create my geometric phone case with a variety of colors and textures. By glueing the triangles onto a sheet of acetate instead of directly onto the case, there’s no messy glue, and you can still see the phone through the case. The best part? Because they aren’t glued directly into your case, you can keep making them and use them interchangeably.



  • Clear phone case
  • Assorted colored paper ( I even used some magazine pages for added texture)
  • Clear acetate
  • Tacky glue
  • Sponge brush
  • Fine tip Sharpie pen
  • Scissors
  • Exacto knife
  • Cutting board
  • Pencil
  • Ruler
