I have modelled and textures a bunch of blades of grass by creating a plane and extruding it slightly, then bending the faces and vertices to get the look of bend blades of grass, these are just so when our worlds landscape is textured it will have 3d assets to make the other models look less flat.

I also modelled a little sign which is going to say fairy realm on it, I thought it would be a nice touch if it looked as though it was painted by the fairies them selves to help with the world building.it is also there to help direct the camera as to where it is going into. The long base of the sign is a square which I extended and then messed with a few of the vertices to give it a chipped off wood look. Then the actual sign parts are two squares which I flattened then have a chipped off look to as well, for the arrow I selected a the faces at the top of the square and extended , then pinched the very top to give it a pointed look, making it look like an arrow head.

And I modelled a well, I was looking at inspiration on sketchfab of little gardens people had made, and alot of them had wells and I thought it would be perfect to go into our fairy realm as it just fit the vibe we where going for,I modelled by well while looking at other stylised well 3d models,I made 3 cylinders and deleted its top and bottom , the cylinder on the bottom and top I just made slightly wider than the middle cylinder,I also bevelled the edges to made it appear softer, then I made a much of squared and cylinders to create the wooden parts that hold the roof up, I fixed them up by extending a few of the vertices. And the roof is another 2  slightly extruded planes.
