Since I have a ton of plants already glued on big 55mm washer, used for jungle terrain, like this one: and our urban table miss a bit of "green".... I have made this Plant pots: so will fit beside infinity buildings. Of course, you could also use like they are a "box" Or step in and have cover from all sides!!!
More tree pot than plant pot considering the size Kidding apart, it work really well and would make great LoS breaker.
