Suggestions for themed altar pieces?

Hey guys, I wanted some feedback from some people who know more about the gods than I do. I'm building up a small business in which I make decorative potion jars, and I wanted to do some themed around the gods for people's altars. I'm very new to the whole pagan thing, and my journey has been very slow as my health hasn't been all that great so my capacity to do research is limited, I know the basics about the gods and what they represent, but nothing really beyond that. I want to make sure I'm being respectful to the gods in making these, and so I figured it would be best to ask other practicing pagans what they would be looking for in altar pieces, and if they have any things they would like to see in pieces like mine, and maybe suggestions on what I could add to make them more personalised for each deity.
