A brand is a very important thing to have for a business and serves many roles. One purpose of a brand is to be a 'stamp of quality'. Here you brand a range of items and this generally tells people that if they liked one of those items, they should in theory like all of them. At the same time it also demonstrates that those items are going to be in some way similar often, or that they are at least linked by a common thread.

Further, the brand itself becomes related to that theme or thread. This then means that when someone sees silk cards with your brand on them, everything they have previously thought or felt about the items they've used of yours is conjured up. This way your brand represents you and is an ambassador for you. It essentially distils the whole experience you have to offer and someone's memory of your business into a single image. This then means that when they see silk cards with your brand on them they do not only get reminded of your products, but they also have all the related emotions conjured up too.
