The floor is extremely easy to cut to size with regular scissors so you will not have a problem going around the nooks and crannies of your room.
You do not have to worry about "grout" when using miniature vinyl tiles. As you glue the tiles flush together, side by side, they create their own "grout" lines because of the vinyl edges. The lines are perfectly in scale.
I went ahead and glued on the kitchen entry door trim. This trim is tricky because it is very difficult to make the inner edge smooth since it's three pieces of wood laminated together. My suggestion is to sand as much as you can, be careful with your floors, and then paint. You will have to do this several times before it gets as smooth as it's going to get.
I used basswood to trim the flooring edges.
I wanted to point something else about bordered wallpaper. If you plan on using ceiling trim, leave the top white edge on your wallpaper so your trim does not cover up the border pattern. Some wallpaper will bring this extra edge for that and others will not. Always take your trim into consideration when applying wallpaper with borders because you do have the potential to accidentally cover them. It's up to your preference and the thickness of the ceiling trim your using as to how much of this edge you plan on leaving. Since my ceiling trim is white, I left the edge on this wallpaper so it blends and none of the border is hidden.
