re: Permanent Duck Blind Question

Depends on what you mean by permanent. What we call permanent typically gets taken down at end of season and rebuilt and possibly moved the next year. If this is what you're doing, you don't really need pilings. Use 10' 4x4s cut in half, and stick them in a about a foot so they stand up.

4x in a rectangular pattern, connect with 2x4's at ground level and top of post, lay plywood for floor. Wrap in burlap, then cover with your desired blind cover.

We always used roseau with willow limbs outside of that to break up outline.
