As you can see on the layout most of the center is empty, there is nothing on the paper. Some parts of the paper only have interesting background that I made with masks but not a lot more. Even the photos are extremely small and don't take a lot of space.
Here are some tips to create white space:1. Don't be afraid to leave parts of your layout with no photos or embellishments.
2. Make sure to create a balance between the full parts and the empty parts of the paper.
3. If you like full layouts with a lot of details try to concentrate those details only on one or two parts of the layout, leaving the other parts as white spaces.
4. If you're a minimalist then concentrate all your elements together so the rest of the paper will be white space. You can add a little glimmer, paint or masking to the background so your layout will be interesting and with depth.
Have fun creating!
