This is what we currently have: It's 4X8 and 2 feet tall. I'd like to expand it both up and out. But hardware cloth is expensive and we live in a wooded area so we need security. Suggestions? I was thinking we could expand up using 2X4 welded wire and expand the footprint using the hardware cloth that is currently on top (we may need to buy a little more to supplement, but hopefully not much). Ideally, I'd like to end up with 50 sq feet on the ground and 6 feet high so we can walk in to clean it. I'd appreciate any help you can offer. Thank you!
