2. Collect inspiration
What inspires you? Do you know what your favorite style is? Create an inspiration folder or inspiration board by saving all the interior images you like. Even if you want to hire a designer, they might ask you first what you have in mind.
Regarding your space, you have to think about what you can change.
They expect you to say whatever you dislike or like about your home. This will help them create a space that corresponds to your needs and tastes. Find a few things (pillows, wallpapers, or even colored rugs) that inspire you to incorporate them into your space.
Delivering a vision board to your designer will also help them to get a picture of what you like, and they will draw inspiration from it.
