The Etsy Forums used to have a "critique" thread where random Etsy sellers could offer critiques/suggestions to other sellers. I got some good (though harsh! haha) advice on how to improve my banner. Why don't we start with a fun/low-pressure exercise?....
"Go to the shop of the seller who has posted/replied above you in this thread. Pick out your favorite item, then post why you like that particular item."
For example, do you like the item because it fits with your taste, the colors, photos, description, or it reminds you of something, etc...? Aside from the number of hearts/views, this exercise may help us identify items with the most potential to sell!
