Putting Netting Over Our Raspberries

We have been meaning to put netting over our raspberries for three years or so, but could never get around to doing it.  Every year we watch the birds go after them and kick ourselves for not doing it again.  Two winters ago a snow drift about 6 feet deep plowed them down, so we didn't get many last year.  But this spring we put in a net over our raspberries on one row.  We have two other rows that are still suffering a little from being wiped out, so we only did the one.  We have been getting about three times the amount from the netted row as from the other two rows together.  So much for putting it off.  We will now be more diligent in getting the other two covered next season.  We had no idea the amount we were actually loosing to birds.  We use a lot of raspberries.
We used treated 2 x 4's at each end and one in the middle.  Over the top we have strung wire(hot wire, wire) in down the middle and at the ends.  Then we have three strands down the sides to hold the stalks in toward the center.  Then nettine is place over the top and down the sides.  At the ends we have little teacup holder hooks, to hook the netting to, to keep it closed.
