Audience
Geolocation
I would imagine the location I would focus on is the U.S. Having to ship outside the country adds another level of complexity at this point.
Age
I believe the target age group would be 35 to 65 years old. This age group would be most likely looking for decor items and have the finances to acquire these items.
Gender
I think I would like to appeal to male and female, but in different ways. Females might be more likely to purchase the items (which would probably be the larger group). Whereas males might be more intersted in ideas to make something similar.
Other
I would want to target those who would want to purchase for their own use. But also there would be a large group who would be looking for gifts. Having content for DYIers would be valuable, because they may want to do it themselves, but this community likes to help each other and that could potentially widen the network.
