Cable protector and organizer

In electronics workshops, technicians have always wrapped tape and fabric around wires to keep the insulation from cracking with constant bending. The cotton sock works by the same principle: it absorbs friction and distributes tension, protecting the cable from aggressive bends that break it from the inside.

Seat or stool covering

Denim upholstery was standard on workbenches and bar stools for decades, because the fabric withstands friction and doesn't fade easily. Modern industrial design today brings this back: visible denim with thick stitching is a café and loft aesthetic. And there's simple preservation chemistry: candle wax rubbed into the fabric makes it slightly water-repellent, an old technique of field workers.

  • The widest region of the jeans the hips
  • Upholstery stapler or tacks and hammer, or strong fabric glue
  • New foam or the bench's old foam, if it's still in good shape

Homemade painting paint

The eggshell is basically calcium carbonate, the same mineral that for centuries has served as a white "filler" in paints and plasters, as in the tradition of gesso and old wall plaster. When ground very fine and mixed with a binder diluted glue, it becomes a matte, good-coverage paint that applies naturally over paper, wood and clay walls.

  • Clean eggshells from 6 to 10 eggs
  • Common white glue school type
  • Water
