This would be a great way to make your own sprinkler system for cheap! I looooove it! All you have to do is make your frame out of PVC pipe, drill small holes in it, along the entire frame, then add a hose.
I totally realize that this probably should not belong on our Window Treatment board and I definitely know that you would not make it with our lace yardage (maybe lace tiebacks in the doorway) but I wanted you to see it. Get your husband to make an inside frame out of plastic sprinkler pipe and perhaps a plywood floor and you finish the rest.
