Tie a ribbon around the base of the hat. You can heat seal or fray check the ends of the ribbon if you are worried about fraying.
Using hot glue, add the leaves, raffia and gourds. This is kind of a trial and error part to see what looks good. In the end, for me, it worked best to glue each individual leaf down. Working with each individual piece wasn’t fast, but I liked the look better in the end.
