How do I shape my turf for it to fit into small gaps?

I bought the Megalawn at 15x7 and I want to make it look like it's in between two tiles in the floor. How do I achieve this? Does it have to be cut perfectly to fit in?

Installing artificial grass strips between tiles has become a very trendy design now days. It is we’ve simple: measure the distance between the tiles and then cut the turf to size along the stitch lines, using nails to secure the turf in place and you are done. If your design pattern permits, try to use longest turf strips possible to avoid extensive cuts and also help the stability of grass.
