Weighted down Screen with Firehose Filled with Sand

[Hickory James]

We have run into issue where screens are perfect but we did not notice the floor was uneven and we go from a 8 ft 10 inch to a 8 foot 7 inch over 37 ft. So we have 3 Bays each with 12 ft screen and was hoping someone may have a solution to fold bottom of screen to back and fill a Firehose with sand and roll up on bottom of screen so it looks great and catches worm burners, putts and is flush to turn in front. We had planned on having fold to front with cord through the bottom tube channel but now that is not an option, as we have too much in front and folded it back behind screen at bottom (reverse engineer) it works good but looks like crap in corners. I have read on this site about using a firehose with sand and hoping to maybe roll it up in bottom of screen.
You can see in picture I have quite a bit of screen and could even loosen screen from top another couple inches, if needed. Bottom line my screens are too long from 4 inches to 7 inches and angled wrong (because of the sloped floor)

Open to all suggestions.
