Mockups are very important elements for promoting your products. They will allow you to have very realistic visuals of your designs on photo or video models. This will allow you to gain credibility and make more sales.
Printing your t-shirts, having a photographer and a model called can take time and a lot of money, which is why using PlaceIt is such a huge advantage.
