They make mats of the stuff you can cut and glue into place, now.
I recently found some in a hobby shop and I fully intend to use them. I'm sure I used the applicator wrong somehow (though I followed the instructions exactly) but was never able to get my static grass to apply standing straight up, no matter what I did, so I gave up and got rid of all that and I'm going with mats, which are way easier to use.
