Cuando llega esta época del año, es común ver mamás y papás corriendo para hacer los tradicionales faroles que llevarán sus hijos el 14 de setiembre a la noche de los faroles, no es secreto que a muchos no se nos dá muy bien esto de las manualidades, por lo que hemos venido al rescate!
Te dejamos una recopilación de algunas páginas donde encontrar ideas muy buenas y económicas para hacer de tu farol, un éxito.
Un lindo farol patrio puede hacerse con un sin fin de materiales económicos y al alcance de todos.
Farol con papel encerado y chispas de crayones. La Nación (@nacion) September 13, 2014
Si lo tuyo no es las manualidades ni la arquitectura, esta pequeñita guía estamos seguros que te salvará de cualquier predicamento de última hora. Lo importante es no dejar de celebrar un año más de independencia de nuestro querida Costa Rica.
