I see lots of great photos outside in grass, flowers, rocks, etc. If you don't want to go outside, invest in a little ring light and maybe a phone stand. That way you can demonstrate the way the product moves and works. I've seen people buy poster boards, a quality sheet of fabric and some accessories (like fake flowers or other decorations). And from there you can make some magic. I'm still on the search for my favorite editing app. But you can use Google and try out the top recommended ones to find yours.
