Greetings all.... So here's my Reno foul in the kitchen pantry.... I was putting up side supports for the top shelf. They are wood and walls of course drywall. Predrilled wood and hand screwed in the anchors.... Two wouldn't quite go in so drilled and presto, hole into the duct behind the wall.... Ok so how do I fix this hole in the duct?

is for the dumb mistake..... Oh well..... Lol
