Just realized my string line was the reason my corners kept creeping, not my eye
Fought a 14 foot garden wall in the backyard for three Saturdays straight, re-laying the same corner courses over and over, before I finally checked the line itself and found it sagging about a quarter inch in the middle. Pulled it tighter on a fresh block and the whole thing straightened out in an afternoon. How often do you all re-string mid-wall, or do you just keep tension on it the whole run?
