The most important thing is to create a guest list. Your event may be open to the public but it’s important to have a clear idea of who you want to attend. Are you looking at your current client base? Do you want to reach new clients? This will dictate how you get the word out about your event. A small grass roots event for current customers can be relayed by word of mouth in store. But if you’re looking to expand and bring in new clients, you need to start looking at marketing options. Maybe you want to contact local bloggers and influencers. These people have large and local followings and it’s becoming more mainstream to connect with them.
