Maybe related or can point you in the right direction. I recently visited an area resort on Cape Cod where a golf course was being renovated. On a tour of the facility I asked why there was so much sand being put down and where the loam or topsil was. They put down atleast 8" of a 80% sand and 20% seed mix...and no loam or soil! Pretty sure it was rolled out. They were planting bent grass (tee boxes, fairways, greens) and bluegrass on the first cut. True they have drainage and irrigation, but I was surprised they were using a mix with primarily sand.

After looking at it, the blades seem a little finer than our Meyer Zoysia. It may be because we cut ours shorter. Common Bermuda maybe? Can you get a pic of the blades attached to a root (stolon/rhysome). It's nice looking what ever it is.

Thank you so much for these ideas and the technical terms ! I wasn't even sure what to google other than 'hinge' which returns a bazillion results, lol. Yes, inboard of the pivot point is the problem I was trying to explain. If I have to overlay the excess not centered to the opening, I will. But that takes my mirror further to the left than I wanted to be (hinge will be on the right). Ideally, the excess would be to the right, on the same side as the hinge, with just a little overlay on the left. When I googled 'overlay partial wrap hinge', I also found these hinges. I think the plate would have to be mounted on the face of the sheetrock, with longer screws that would go thru the sheetrock and screw into the studs, but would these work ??? It looks like they would allow the mirror to have a very large overlay on the right and also the hinge would be hidden. http://www.hardwaresource.com/hinges/cabinet-hinges/blum-european-hinges-grass-european-hinges/blum-compact-33-hinges-and-mounting-plates/blum-compact-33-face-mount-plate http://www.hardwaresource.com/hinges/cabinet-hinges/blum-european-hinges-grass-european-hinges/blum-compact-33-hinges-and-mounting-plates/compact-33-hinges I see the hinge is supposed to be inserted into a drilled out cup. Vice versa, could the face plate be mounted on the mirror, and the hinge cup be drilled into the sheetrock ? Would the hinge still open correctly ? The reason I ask, is because I am not sure what material the frame of the mirror is made from and also if it is deep enough to allow me to drill the cup. Lateral hinges I think would not work, for the same reason as the drawer glides mounted sideways - I don't *think* there would be enough room. We're down at the beach house right now (our last guest broke the side rail on one of the bunk beds and we're here fixing it, no idea what they were doing to break the rail lengthwise all the way from end to end!! kids jumping on the bed I would guess), but I can measure for that idea when we get home tomorrow.

Unfortunately I am not able to determine the grass type from that link because the grass is so small, I cannot see the characteristics listed in the link. The only thing I could determine is that the leaf blade tip shape is pointed and that it has stolons on the weird grass. I don't have a microscope to see the rest of the characteristics. Anyone else have some ideas to share?
