I had one on my flat bottom for a lil while best advice I can give you is do not put any kind of wooven grass panel on that blind resons why.
1 It will make the blind heavy as a sin.
2 It will make it very diffucult to properly fold down the blind
3 It will hang out the boat when driving and grab water.
4 It will make the blind profile stand out and look like a huge box.
Best way to camo it is use the camo skirts that come with it are use some camo netting.
And add grass that comes in bundels, pull the bundels apart and ziptie them all over the blind use diffrent colors as well.
Start at the very top of the blind and work you way down.
Hope this advice helps sir.
