Great product,  covered a small area, but did the job of what I needed... my use was to adhere it to a backboard along with stapling the grass against it to hold in place. The twist ties didn't work, nor does the plug in place part of the product holds up for a solid tight finish.  . Best bet if you using it for a wall surface or effect is to use the method I suggested. 

Purchase a corkboard or flat board and use staples in between and a little bit of gorilla glue on the edges...flip and use a utility knife to edge it up or cut the excess  off.   You should have a clean product. 

Also the grass is dark and not as bright in the pictures.   Best luck with your order
