I have used photos from our trip last year to Joshua Tree National Park. We took a walk in Hidden Valley and here are my layout with photos from that walk:
And here is the sketch:
For my background I used about 1 1/2 piiece of 12 x 12 paper, cut them in strips, distressed the edges and adhered.

Together with the flowers I used some green leaves from the same packaged and I cut out some leaves in barlup for some extra interes .
I put my journaling on a piece of cardstock.
I put some chipboard in two of the corners. The chipboards are colored with gesso and some color from Shimmerz.
