Very helpful lesson! I've had my RedBubble account for quite some time but I only had two images on it and I was convinced I will not sell anything so I stopped posting on it. 

But you made me think I can actually sell stuff. The Pika I created today and I am about to upload one more image today. What do you think, if I upload like two images per week will it be good?

Please give me your opinions on this.

Thanks!
