The problem of pop-up blinds
The first problem is a pop-up blind, is that it isn't in anyway a permanent structure. Keeping them out in the cold and rain and snow isn't meant to work after awhile. It's good for what it does; nothing more.
Knowledge is needed to brush them in; hide them better. Knowledge is needed to repair them. A limb falling on a blind will do wonders to a blind. A Mr. Fix it can keep it operating, as long as possible.
A $100 or $200 structure is just that. It's the attempt to make it what it isn't, of some great permanence, that's in error.
