When you say front of the TT do you mean where the doors and awnings are? If so the following may help.
We bought some sunshade material from Lowes. My wife cut and hemmed the material to fit the TT awning. Like someone said she sewed gromments into the bottom of the screen. She sewed some attachment clips in the top that slide right into the awning groove.
Very inexpensive compared to pre made and you can customize the size.
We have had a number of people stop by and want to know where we bought the screen.
