I believe that using Celtic art in garden design can improve its look and atmosphere.
For my own garden design I placed large hand painted rocks among plants and shrubs. I also used bark chippings and small stones for a path.
To continue with the Celtic theme I painted a wooden flower planter which my father-in-law had made.
For the side wall I created a Celtic themed picture. Then I placed a small table and chairs to encourage visitors to sit and relax.
I have included a quick video of the newly designed garden path area
Here is one of my Celtic rock paintings in its early preparation stage. It will have gold and dark red paint added later.
