This looks good.
I got a photo backdrop a few years back as it was super cheap for the size. I found the material a bit stiff (even though it's thin) which didn't sit very flat, nor allow hills to be placed under it. I might give it a wash to see what that does.
I the end I got a deep coat mat (probably 10x the price) which gets used frequently due to it being flexible 'normal' material and having grid corners printed on it.
