Redbubble is an Australian Business that offers a print on demand site for artists. I have a store online with them. I upload my images and select which products I want to use the images on. All the rest is up to Redbubble (taking payments, making product and posting out), and I get a small cut for each item that sells (it all adds up and helps pay some bills!). Keep an eye out on their page too, because they often have good deals of 20-30% off with the code word at the top of their page. Definitely order by the end of November though if you want your items for Christmas! Take note of your delivery date when you are going through the payment process.
They have products such as cushion covers, tote bags, clothing, phone covers, bathmats, scarves, shower curtains, clocks, mugs, prints, greeting cards, etc.
