As always, thank you for the information Bill. I should be receiving an aquaculture sample pack(netting) next week. By the end of the week, I hope to have my order in. As an FYI, I measured up some of the neighbors kid's hoola hoops and they were a convenient 3' diameter. For top frames, I thought about doubling them up to add some rigidity that is until I found some 1" i.d. black plastic well pump pipe I had lying around. With a plastic barb fitting, the black pipe may become the top frame of choice. I will post the outcome.
