I had to laugh. We've all done it, haven't we? We push on, even though our gut is telling us we're on the wrong path. The rationale can be so silly: we bought a whole gallon of the paint, the store for replacement is closed, it will quilt out. Pretty soon we're so far in that going back seems impossible. So instead of trusting ourselves enough to quit at a false start, we plow on until there's no way to redeem the project. Not only is the project spoiled, but we had a miserable time doing it!
We don't know what to do next, it's a good quality stain, even sand blasting hardly made a dent. I'm hoping that a little weathering will do the trick. Because I'm an incorrigible optimist I'm hoping that an answer will present itself next spring when the snow thaws. Keen eyes will notice the stone stairs going in at the top of the hill. There are a few more steps to go, but by next summer we'll be able to easily get around in this crazy, vertical garden.
