New Grower/Daft Qustions

you can build a simple 4 or 6 post bamboo cage (depending on the length of the area you want to cover). get metre long bamboo put a small split on one end of the bamboo with a knife and in the slit slide in your net to hold it in place and job done. all you need is a big net that will go over the top and run down the sides. half a metre or a metre long bamboo would be fine. at the bottom, get some broken bricks and put them in place.

when finished it can be easily disassembled and put away.

any more questions fire away or have a search on the forums, there's plenty of info here and on the web.  

hope that helps
