Right all you webby people. I'm wanting to put together a Wordpress e-commerce site. I have built up a stockpile of orphan t-shirt designs over the years so I thought I'd set up a store. It's mainly as a project for my two boys given the lack of paper rounds these days plus I think they could learn a lot along the way. I'd preferably want use Shopify as the t-shirt printer links well with it. I've seen quite a few free themes that look like they'd do the job but is there anything I should be aware of before I start?
