I will be the first to admit that it feels really weird to scrap a layout without a picture but it is also very refreshing at the same time. This allows my journaling to be the main star of the layout. In this case, it allows my journaling to voice what it needs to without a picture to distract the viewer.

So don't be afraid. Take the challenge and scrap a layout without a picture. I bet you will feel just as refreshed as I did when I created mine.
