Mrs. G.,
I want tomake sure you know that perforated bags offer no protection against PC, OFM and CM if your fruit touch the side of these bags. Those pests can lay eggs through these bags.
@northwoodswis4, your are in a colder zone. Smaller holes for water draining purpose is sufficient. In a warmer zone you need a wider holes to help with ventilation, too.
@Auburn made his own multiple hole bags, working perfectly for his warner zone.
