Robin, I have found that those exact things you are doing, netting and flashy things, are the things I do, too, and they've worked very well for me. I use cable ties to fasten the netting to the wood, and to conduit trellises, too.
If you can borrow a conduit bender from an electrician, it's the cheapest, sturdiest thing I've found to use in the garden. It's $2 for a 10'stick, and that makes a 3' high trellis over a 4' wide bed, or, I use them with a joiner, and have 6' high hoops over an 8' long bed. Once I figured out the math, it was easy to bend the conduit to the shape and length I wanted.
Sounds like you're well on your way to success. Let us know how it works out!
