Shipping from your store to the customer, when I get t-shirts in the mail they come in a plastic envelope via USPS. For single items this might be the best way to go.
Considering the nature of your product and your collective you should look into starting a store on Etsy.com. This will give you a good slow start and experience selling online. Also, you may receive feedback on your items which will help you when you decide to launch a dedicated merchant solution. I understand Etsy may not be as advanced as your goals are but every journey begins with a single step and selling on marketplaces is a good first step.
