Design is an inherently creative faculty. It requires the designer to imagine and visualise, whether it is a product, an image or a space. Interior design involves visualising an interior space and then realising it.
As an interior designer, you will need to know not just the aesthetic aspects of designing a space, but also the practical aspects. For example, an interior designer needs to know how colours interact and how visual composition works, and also have knowledge about electric fixtures or injection moulding and how it could be used to create furniture!
What I'm trying to say is, as a professional, it is necessary to know the technical aspects of your field as these will limit or open up new possibilities. Also, it is important to know the various players in your field. For example, along with the knowledge of the process of injection moulding, you may also need to know about who provides it, such as Daneplast plastic injection moulding.
As a professional in the creative field, it is also important to keep up with the industry. A professional always needs to keep abreast of new innovations or possibilities in their chosen field. This allows you to experiment with news things and remain dynamic.
Interior design is a highly inspired field and can be a rewarding and satisfying profession for creative individuals.
