As a homeowner, one of the biggest challenges that you are likely to face is making sure that your home matches up stylistically. Some of us prefer more quirky designs that don’t particularly “go” in sync with normal fashion and trends, but that’s perfectly fine. What will never look good, though, is specific elements of the room that just do not reflect the rest of the room at all. Contrast can be effective but especially when it comes to things like blinds, it can be counterproductive. The next thing you need to determine is the arrangement of the blinds, in this case, vertically aligned blinds or horizontally aligned blinds. Both have its advantages and its really up to the owner to see how it fits into their overall design of the space.
Sometimes, what you think is the best choice available could be absolutely trumped by a better choice with a little bit of research. If you have a specific need for the blinds i.e. to reduce the amount of light entering the room but still have a small bit of sunlight seeping through, a blind with horizontal slats might be what you’re looking for. Something like a Venetian blind. Look into the characteristics of each style that you have considered in a deeper fashion, as it will pay to know the pros and cons of each type of blind outside of how it looks aesthetically.
