I used to use old water piping stuck on metal poles that would form an arch and then drape netting over it.  My new Allotment, I will use green rubble netting.  Wooden stakes buried into the ground then cable ties to hold the netting on seem the best way.  Or is it.  I've tried to aquire road pins but these seem expensive.  Any help or designs would be great.
