Is Selling On Redbubble Worth It?

It's worth it, for now, for these reasons:

• I can see my designs on products that I will most likely never produce.
• It's free to list.
• I'm not required to upload a certain of designs in any time frame.
• I can be as absent or as active uploading designs as I want to be.
• I always retain the copyright for all of my design. 
  
• There is no contract and I can leave the site whenever I want.
  

These features are generally for any POD venue. I just happen to be at RedBubble.

I also do other things with my designs. I create printables and digitals for my own shop. Diversification is key for me. If I was designing and only selling at RB, I don't think that I'd be successful enough because of the volume of sellers. I also abhor designing for trends and popularity. I want to design what I want. What makes me happy. I am trying harder, though, to occasionally incorporate some trending ideas and motifs into my work. 

If you regularly study trending ideas, motifs and designs and cleverly incorporate them into your work, it will help increase your sales.
