You can showcase straight away with your sign-up kit. This contains all the products and marketing materials that you'll need to get going, plus it all fits into your MyShowcase canvas bag.
In addition you may have some lightweight marketing materials, such as showcards to display at your Showcases. As you get to know your clients you may wish to add to your kit to meet their preferences or requests.
You could also add some of your personal favourites to your kit, but try not to overwhelm your guests, allow your clients and customers to discover more when they book another Showcase.
