We used 2 foot post spikes, but you could use deck blocks which are cheap. We made 8 X 4 panels with viny lattice that we stapled to the panel. Then used cheap brackets screwed to posts to slide the panels in.
Go natural "Quirky panels built from fallen twisted willow branches imbue this garden with personality. Their organic forms and weathered patina meld beautifully with plants. Both see- and eye-catching, these panels screen, delineate and frame the garden “rooms.”" - Canadian Gardening
These lattice panels create privacy in the garden while serving as a sturdy trellis for climbing roses. Simply tie the roses to the panels with twist ties. Arched panel tops and finials on support posts provide attractive finishing touches./
