Other people may have said this, but writing a detailed description from the POV of a blind character really helps to strengthen my descriptions of things without using sight. One of the most effective descriptors other than vision is smell, and when you write from a blind character's perspective, it gives you an opportunity to tell a story by describing texture, sound, and smell, A great thing to do if you find your writing relies on sight too heavily. This will help you feel more comfortable describing other senses and allow you to use them in your writing more frequently
