Thank you all, it´s good to know that the nerves is okay and normal.
It´s just when I go see demo´s they don´t seem nerveus at all. But I guess they are.
It´s so good to know, that I´m not the only one, that´s scared this time.
Breezy and Rach I´m very pleased with your advise.

And I will pratice what to say in front of my cats. my dog can´t sit still for that long
The note thing, is a really good idea. and I will lay a list with names of all the flowers I use. Because at somepoint during the evening I´m bound to go blank.

for the end of the demo I´m going to make two very large bridal pieces . Since the wedding season is starting. hope the size of those two things, will impress them.

The rest of the designs is concentrated on sales design. mixed with three showpieces, that might be used for windows displays.

Fly2high is right about the pride. I take my work very seriusly. sometimes so much that I laugh at myself.

Anything else come to mind. please say so. also if something went wrong. Any kind of comfort is more than welcome.
