A school tie represents uniqueness and identity. No one school tie is the same as another because of the school crest.
When a school opens, much thought goes into the crest, it represents the very core of its formation. Most often, this crest is used in some way or another on the school tie. So when it comes to designing the school tie, much thought goes into the layout, colours and where the crest is positioned.
Generally, the colours in the crest will dictate the colours of the school tie, with the most prominent colour forming the base of the tie. In short, most often, the school tie will be completely representative of the school crest which is one of the most valuable pieces of property the school owns.
