I started this activity on the 20th of September 2016, on ex- French market place dedicated to hand made, and called “AlittleMarket”. And then, on ex- German equivalent: Dawanda, and Etsy.
On Etsy, I received almost 600 reviews (as of Dec’19), which include those from Dawanda.
On ex- AlittleMarket, I had received 80 reviews, till the closing in August 2017 (i.e. cc 8 months after my start).
