Hi,
I always ask customers to please consider taking a moment to review my shop, item, and customer service in their Etsy account, top right, under "Purchases and Reviews"
There you can click on items you have purchased and review them. The 5 yellow stars are at top of the item photo and you click on the star you wish to give that item, the best is the 5th star over to the right!
You than can write in the box what you would like to say about your item, the shop, the shipping, wrapping, friendliness of shop owner, etc.
Hope this helps!
