Taking product shots on a sheet or fabric creates lots of problems @hobbitgirlie1880 because it normally always leads to creases and shadows.
It’s much better to shoot on a nice wooden table or if you want a more simple look use a piece of artboard which you can pick up in art shop - a pale grey artboard normally works better than white. Again, I would think about introducing some props to your photos to give your work context and give buyers a sense of scale.
Have you thought about asking other sellers on the forum for their thoughts and tips? We have a product photography section, where you could start a new thread, or use this one Product photography crits - put your product shots up for review!
I hope that helps. I know product photography can be one of the hardest things to get right, but it’s also probably the most important when you sell online, so it’s brilliant to hear that you want to achieve the best images you can.
