Looks like a nice selection for your flower garden!Ha! Thanks. I actually did some sketchwork visualizations for these Zoas as well.
I started with the individual pieces over my rockwork looking for placement and combination ideas (along the bottom)
Then once I had a sense of where they would go I simply started looking for the best color combinations using larger images.
This was all done using Google Slides, a free PowerPoint type of application. It really helps me get an idea of what I want and don’t want. I will let them open and get a sense of their true color before glueing anything down. Using the visualizations above will help me from ending up covered in glue trying to decide what the heck I should do.
