Yep, i bought my tennis balls today! Will be constructing a cage from canes and tennis balls. Have also read in my books that net curtain does the job too. Although this would not look so good. The spring cabbage i have in at the moment have been hand picked and are going great at the moment. However i am still picking off some catterpillars thought they would all be gone by now.
Good luck with your cage.
We will all have to post some photos of our constructions when they are built.
