CMG:
Awesome job on the weathering, I wouldn't do another thing, they are perfect.
"The enemy of good is better."
(A saying by an MD friend of mine, meaning when you have a good result...like in a complicated medical procedure...don't mess it up by trying to make it better

)
And when we originally made our cemetery fence (which is nowhere near as nice as yours, just warnin' ya) I couldn't get the skull whistles, (every supplier was sold out), so at the last minute I made finials by cutting black craft foam into an arrowhead shape and sticking them down in the PVC. Looked OK. Better in the dark
