The Geo cloth looks great. The large pleats are very important, they will facilitate lifting and crawling under. I like the way the flat black draws attention to the RR.
However, for me, I'm unsettled with any enclosure. I do not like spiders and I absolutely hate large basement spiders and camel crickets, so I am reluctant to give them any hiding place. I spray the wall's base and set out glue boards. If you want a shocker sometime, place a few glue boards around the floor under the layout and check it out every week or so. Yikes!! Maybe it's just me.
