For the first, I would probably do a burlap drum shade (the shape reminds me of a mid-century lamp we had when I was a kid that had that sort of shade).

The second one is so tiny. It needs a clip-on shade. I think I would do a tapered shade. I could see black or white. I think it would look cute with a patterned shade, too, but that might take away from the base. I'd look to your decor for guidance on color.
