To save on space and create a great trellis that is cheap, strong and easy to put up follow these steps:
You will need
4 x wooden blocks (these are used as mounts, so make them and big or a little as you wish depending on how much you want the trellis to stick out.
1/4 inch wire (this is the trellis part, so make sure you measure it to the size of your fence)
16 screws (to screw the wooden blocks to the fence)
4 hooks (to secure the wire to each block.
Attach four wood blocks to the fence (one for each corner of mesh).
Screw a lag hook into each block
Fit the mesh over the hooks
