I want to sell a clothing product and it is based somewhat on the eye masks that we use for sleeping when we want to keep the light out. These eye masks have unique designs on them and that is the part my product would use as well. I would not be copying these eye masks.

The product I want to sell is already being sold but I would be selling it with designs on it. The eye masks that became a fad were unique because they had designs on them. I am hoping to start a fad that keeps on selling.

What steps do I need to take? Can my idea can be copyrighted or patented? Where do I begin?
