If you're a member of TrendsalesClub, you can add a cover photo to your shop as well as a profile description where you can write more about yourself, your style, your sizes, you preferred trading method and etc.
In order to add a cover photo, go into My Profile > View and edit shop.
When you're on your profile, you must click on the cogwheel icon in the top right corner.
This gives you access to an editing site, where you can add a cover photo from your camera or library and add/edit your profile description to make your shop unique!
It's a good idea to write a little bit about yourself and how you like to trade to let other users know what kind of seller you are.
