Zazzle is a marketplace where you can easily add you own graphics to products they provide. It’s a low cost, pretty effective way to make a few bucks with your works. However their ToS might not be for everyone.
I firmly believe in distributing my art and designs. Money is secondary, I am a concept artists, which means I worth ship the ideas more than the actual piece. I am a true believer that once you have an idea, write it down and publish it that idea belongs to you, everyone else is just a copycat or the guy who re-produces your artwork.
Nevertheless I have not earned a fortune with Zazzle, which is probably because I have neither actively promoted my shop, nor had any items in it until recently.
You can see the items I have created so far in my little shop.

The advantages of Zazzle

You don’t have to be a Jack of all Trades to be successful at Zazzle, their system is very easy and you can build your products with basic knowledge of a computer. It’s great for creatives who are starting out and don’t have great deals or produce everything themselves.
It’s extremely fast. In case you already have graphics you can use for print design you are ready to go.
You have your own ready to go shop with featured items that you can link to from your own site. People can find your stuff directly on Zazzle or you point them to your shop and earn even more in case they sign up and buy from Zazzle’s referral program.

The disadvantages

The shop looks a bit dull, even if you customize it, but most webshops do so it’s not really a biggy.
You might dislike the ToS of Zazzle concerning the use of your art.
To really get it going you have to market your shop and refer other people to join the site, or you have to create such a killer stuff that other people do the marketing for you. It’s great for people with a very low budget, but you have to get people to buy your stuff, most of the marketing has to be done by yourself.

Money Making Potential for Creatives?

Creative people can make some money using Zazzle, that’s for sure. It all depends on the contents you deliver. In case you create great stuff and are able to promote it well you can earn a few hundred, maybe thousand bucks per month. The key to selling is that you have to do more than create the items, you have to promote them somewhere.
My Zazzle Money Making rating is 8/10, as you can define your profit range on products. The problem is that the consumer decides if your items are too expensive or not, and that might happen if you up your profit margin by 50%.
I can only recommend testing it yourself in case you are producing digital artworks en masse. I am a fan of the digital lifestyle and the possibilities of passive income streams that can be created easily and are no hustle to maintain, Zazzle meets these both criteria, even though I did not earn a fortune with them, at least yet.
