Landscaping, porch side

There are some challenges with the landscaping. The lovely grass sheets have to be cut and fitted around the building and kiln. The sheets have a directional grain. The grain doesn't always run in the direction it should, which results in obvious breaks between sections. Not realistic at all. If you look at the strip to the left of the garage door you'll see what I mean.

Also, I haven't figured out how I'm going to make the driveway and walkway to the steps. I don't like the painted stone-finish paint. Another issue is the too-clean lines between grass and man made areas. The pads by the doors are bits of a plastic foam egg carton. They look like concrete pads that might lead to strips of concrete with grass between.
