Tip 1: It's not done until the cap is on. Yes, they do make cap-block finishing parts. If you did a block and all of a sudden you put maybe a blue stone cap on it, and you cemented it in, you can come right up to the top with that. But if it is still going to be a block that is just placed in, you may want to hold down the top soil since it is finished on all sides, unless the landscaping doesn't allow the look for that.
