Certain bedding sells well, I have sold a few duvet sets. Random items too, it just needs someone that wants what you have, always worth putting it on there with good photos and description, but no tat. I have seen manky oven gloves and scruffy, bobbly clothes.
Clear photos, I do use a mannequin, but also take photos of items laying flat or on a hanger because sometimes people want to see them that way, also include measurements of every part of the item, the one bit you don't include will be the one that someone will want to know.
I do not sell shoes, consistently problematic. Anything else I will list. I have sold a variety of weird and wonderful items over the years, pet things, clothing, bedding, craft stuff, art work, china, ornaments, bags, exercise stuff, anything that is in good condition. Sometimes it takes a while, sometimes it goes straight away and I think I under-priced it.
