You will need one or two food mats, depending on the size of the mat; a glue gun, 2 hair clips, and for adorning: ribbons, fabric flowers, feathers.
Cut one rectangle of 24,5 cm x 10 cm for the body of the hat, mark a line of 1 cm on the top and bottom and cut triangles along it so you will have a good base for gluing.
Cut 2 big circles of 11 cm of diameter and 2 small of 7 cm of diameter.
Glue the edges of the body together with hot glue using a small circle as a guide. The body should be wide enough to accommodate one small circle inside it.
To make the brim, cut a hole in one of the big circles using the diameter of the body of the hat as a guide, it should be more or less 7 cm of diameter. Glue the body to it.
Attach the hair clips to the other circle and glue it to the brim. At this point we are almost done...
Glue some flowers and finish the edges with ribbon...now its done :)
