Well, my Dawanda experiment officially ended today, when I e-mailed support to cancel my account. I know that some will say that 4 months is not a long time to experiment with a venue, but I need the time to concentrate on my own website and my Etsy shop. Especially my website, which has been seriously neglected for a long time. Dawanda is probably a pretty good venue for those who can list and communicate in French and German, as their English site is known for not getting as much traffic as the others. I appreciate the fact that they had selling/traffic stats available to individual shops, as well as the ability to use a previous listing as a template for a new one (helpful when listing new colors of previous items), but the overall store and site just were not right for me.
I may choose to branch out onto another selling site sometime in the future, but for the time being, I will be staying on Etsy.
