Pete, First congrats on being asked. You must have skills and tie well or you probably wouldn’t be doing this. I’ve tied at shows for many years. A lot of good suggestions above.so some of these may be repeats.
Don’t bring the store with you. Bring just enough to tie 3 or 4 patterns and as someone said have “kits” made up so you only have to pull out one bag of material to tie a bunch of the same fly.
Keep tools to a minimum. You don’t need 6 bobbins etc.
Have something that keeps your head cement from tipping over.
Bring an extra light bulb for your tying lamp. Bring as light weight a lamp as possible to cut down on space and weight. I now use a Mackensie attached to my vise. I love my Girraff systems and other Day Light lamps that I have but all just take up too much space. Bring a extension cord and a outlet ‘bar’.
I bring a small hand cart to carry my stuff in on.
Bring a small cooler with a few bottles of water in it and a snack or two.
Have a small display of your finished flies that you will be tying. You don’t need to bring a hundred flies. Keep it simple the first time.
If you are going to sell flies, have some business cards or cards of a similar size on hand and a pen or pencil as a lot of people will want a signature even though you may be selling fishing flies a lot of people are sticking one or two away for their collection.
Drink Decaffinated coffee if you have more than one cup in the morning and be sure to eat something with it or you hands might get a caffine shaking.
If you are going to sell flies or give them away be sure to have some zip lock bags, small plastic boxes or other containers to put them in.
If you are going to sell flies, know what you want for them ahead of time…don’t hem and haw.
Bring along a small sign that says “BACK IN 15 MINUTES” that you can put out when you need to take a break.
Talking to people as you tie is important. Ask them if they have tried tying what ever fly you happen to be tying.
Or if there is some part of the fly you are tying that they are having any trouble with.
Get to th show early enough to set up.
If the show is more than one day bring a lightweight cloth to cover your tying area with. That way you don’t have to pick everything up at days end.
I usually see if I can get an extra stool or chair so the box I keep my extra stuff in is at arms length and I don’t have to keep jockeying on and off my seat to get something. Or have everything in 2 boxes and set the empty one that held everything you just put on the table on the floor and the other box with any extra ‘kits’ or material, or flies on top of it.
Tie flies that you are comfortable with. Save the difficault ones until you are at ease with tying in public.
When you are on the tying side of the table YOU are the expert, you are the instructor, you are the one showing your tying sequences , methods or tricks. Speak gently, without bravado but with authority. People will respect that. Be open to qustions but be ready for the one in a hundred guy who will try to tell you his way of doing what you are doing. Nicely say, that thats another way of doing this but I find this to suit me better and continue on speaking to the rest of the crowd. People have paid their way in to see how you do it, not the loud mouth.
At the end of the show don’t forget to thank the promoter or host for inviting you. Doesn’t hurt to give him/her a couple of your flies as a thank you.
Most of all try to relax and enjoy yourself. You will get used to tying in public in a short time
