  • Etape 1

    Report the two forms below (download from the blueprints/plan section) on the cardboard and cut them with a pair of scissors.

     

    With an awl, make small holes in the shoes.

     

    With the eyelet pliers, cut the holes at the back of the shoes and fix in an eyelet (the eyelet is not absolutely necessary).



  • Etape 2

    Paint the two cardboard bases.

     

    Pass a coloured string in the holes to form shoe laces.

     

    With contact glue, fix the two glasses ont the feet.

     

    Decorate the glasses with self-adhesive plastic to create faces.
