It might be a good idea to go to some exhibitions and have a look at what others are doing, and then asking some questions. I notice that the Marlow/Maidenhead exhibition is on this weekend, and members of this forum are exhibiting there, so don't be afraid to ask, as long as they are not too busy operating. If you can't make this, then in a fortnight there are shows at Guildford (Astolat) and Tolworth. Guildford is a smaller show, but very friendly, as I know, having exhibited there myself!
Hope this helps.
