I put up some trellis sections under Alison's house on Bainbridge so that plants would have
a place to grow up on. We went out and bought pre-made plastic sections of cross sectioned trelis.
A single section measured 4' by 8' and cost about $20.
The thing that made this project interesting was getting the sections to match one another so
you couldn't tell that there were two seperate pieces of trellis as shown below in Figure 1.

Cutting the trellis was amazingly simply and a hand saw cut throught them quite easily. We just
cut it right on the lawn with the hand saw as shown below in Figure 2.

Next we put the trellis sections up on two sides of the house and tacked it in using finishing nails.
