The sign for bouquet is done by first signing "FLOWER" and then
using a classifier type sign to show the flowers bunched together at
the base and sticking up into the air.
Note: That facial expression can vary. Heh. I'm using a bit of a
dopey facial expression as my way of showing a light hearted
offering of flowers.
