Sorry, but you need to atleast have 3 Trainer Cards on display if you wish to make a thread showcasing them (with the exception if you've made a completely original design altogether, then you're allowed to showcase even just 1 card) otherwise, you may post single Trainer Cards in the 'T-Card lounge', I told you about it before, so you know where to go.
Refer to the rules if you wish to know anymore details. If there's anything you don't understand, then feel free to PM me. I'd be quite glad to help. :)
