Must be hard to build a blind there.
Prior to paying attention to Huds posts I thought comments like this were rude—and they usually are, at least a little. Now I know he’s just trying to be funny— and he usually is, at least a little.
Back to topic—I agree with PMK we need more info. I assume when you say “build” you mean garage build cheapo wood blind. Quite different from custom fabricated high end blind. If you want a good answer you need a good question.
