This is at my house and leads up to the back door where I am doing a large paver patio. The caps are Mesa and are normally 18" wide 12" deep. I cut them down to make the circle less rigid. I am considering redoing the caps on the top and only having 4 where I now have 8. I will be adding slate colored pavers to the top behind the caps. What do you think, ok or redo them?
