I ironed fusable web on to the back of the dark brown felt.  I found an image of a tiki cup online and sketched it out on paper.  I cut out the areas that would allow the lighter color of felt to show through.  I placed that on top of the dark brown felt and used chalk to trace around the cutouts.  I then fused the dark brown felt to the light brown felt.  I made a seam up the back and then placed a circle of cardboard inside the felt about 2 inches from the top.  I clipped the edges and then glued them to the cardboard.  I cut out a place for my head to slip through and holes for the parasol and straw (made from a wrapping paper tube).  To cover up the cardboard I used celophane wrapping paper bunched up to give it the look of a shiny fluid.
