I havve a ceiling light upstairs:

It never had a shade, so I bought a new to me used one:

The bulbs I had were to big for the shade to fit, so I went to the hardware store to get some smaller bulbs and a cap to secure the shade:

The smaller bulbs allowed the shade to go onto the light and the cap was the right size, but the cap was smaller than the whole in the shade and therefore would not stay on. Back to the hardware store I went for a ring:

The ring looked like it might work, but the ring is just thick enough that the cap won't go on. There's a flat 2.5" part on the bottom of the shade where it looks there should have been some kind of ring to hold the cap, but there wasn't anything at the hardware store. Is there some cap I can buy that will be big enough to cover the whole and perhaps the flat part on the bottom, but still thin enough to fit on the post? Thanks for any help.

 

Menards should have something in their lighting department, usually in one of the short aisles with the light fixtures. Get one that is large enough so that no washer is needed.

Otherwise a new light fixture probably costs about the same as a replacement globe, if you can return the globe.

 

If the threaded stud in the center of the fixture is too short they usually can be adjusted. Turn off the power. Then unscrew the fixture so you can get to the back side. You can leave the wiring attached but there should be a nut on the top side you can back off so more of the threaded rod protrudes to hold the globe.
