Row cover can become kites

Unfortunately today one of my row covers became a kite and blew of the bed.  If the row covers can not make it a week I do not believe they will be lasting years to come.  The point on building these and testing them is to find a way we can do this every year and be able to re use frame and cover for as many years possible.  I have a plan for row covers that I think may be better that I will be trying this weekend.  I am still looking for the perfect way to secure plastic and be able to open them and get our harvest. You can not learn if you do not try!
