Hi Zeynep!
Happy you're into the group!
If you're starting, you shoud check in "ETSY-HELPING ETSIANS PROMOTE" -->
https://www.facebook.com/groups/226851564163654/ There you'll find lots of information about how to improve your shop and you can freely ask members to take a look at your shop. They are very active and generous and with more experience than I have.
I'd like you to stay here and if you are able to start a similar collaboration like the one I just finished (GET THE LOOK BY ELSIE VON CRAFT 1) it would be great!
Wish you all the good luck!!!
Elsie
