A tricky subject but I think you are on the right lines with the first collage of three. I like the idea of an overall wide picture and a couple of close-ups.
Just ensure that the ‘levels’ and contrast is brought up to give the photo more punch.
If you are doing a wider shot like a mini-panorama, crop it so that the item does not have loads of free white space below it or above it. I do lots of panorama images (Not on Folksy), and a tight crop makes a huge difference in the final picture. The proportions of the panorama wide shot can be important, so please experiment.
The overlapping collage doesn’t work as well for me.
I agree that you should try to use something like a fireplace or prop to enhance the picture without dominating the image.
A wide, banner type image can look impressive.
