Simple, but very effective. Think about hospitality for your guests, the people visiting Seedy Saturday including your display people. Food provided by a local catering service provides healthy food items for sale. The refreshment area is a great place for folks to share information on growing plants, etc. Make sure you have an area near to the 'seeds to swap' table where folks can sit, talk about plants, etc and have a cup of tea.
Advertising is important.
Make up a pretty poster that you spread all over your region. Make a one page press announcement and send it out to every radio show, paper, etc. If you want some sample ideas on posters, press releases, etc please contact the address below. If you need some information on the political issue of seed work, or need to find a speaker for a radio or television interview, contact Sharon Rempel at address below. Display people can make or break the event.
