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.
I think a shorter version of this would be great to either keep our dogs in one area of the back yard, or to provide a separate area for Madelyn and other kids to play. The entire yard is already entirely fenced in via chain link, but I think I need to take a divide and conquer approach!
