• cardboard
  • double-sided tape
  • wheat flour
  • white wine vinegar
  • cardboard and recycled paper from magazines, newspapers, etc.


The objective is to create recycled paper tiles to insulate the walls in our home, and create more comfortable rooms. Instructions:

· Design the template on paper, setting size, shape and distribution of the paper tubes.

· Cut out as many modules as necessary from cardboard. You can use cardboard of similar thickness or different thicknesses, playing with volume for decoration.

· Roll the sheets of paper into tubes, gluing the edge with natural glue from a mixture of flour and vinegar (instructions here). We can choose the colour hues of paper for best matching with our decoration.

· Fix the paper tube to the cardboard and spread the glue on the paper tubes once adhered, to harden them.

· Stick the tile to the wall by using double-sided tape.

The thicker the cardboard is, the greater insulation we will get. For maximum insulation, we can add a layer of any insulating material between the tiles and wall, for example, cork panels or recycled textile.

Instructions for making natural glue:

Fill a pot with 2 litres of water and 8 tablespoons of flour, stir and boil the mixture for about 15 minutes to allow all the lumps of flour to dissolve. Next, we will beat the mixture and put it back on the fire at a medium temperature for some more time, stirring frequently with a wooden spoon to avoid lumps. If the resulting mixture turns out too thick, we can add a little water. The texture must be close to compote. When mixture starts to boil, just lower temperature and add vinegar. Let it boil a little more over low heat for about 5 minutes and then remove.

Finally, we liquefy all again and when it gets cold, can be strained to achieve a finer texture.

This mixture can be stored in the refrigerator for a few days in a tightly covered plastic bowl.
