Using a thank you notes is a bit unfamiliar habit to Estonians. I know it’s popular in US and a lot of other countries, but people here usually don’t send than you cards.

So when I started on Etsy, I had to learn that sending a card is a good customer service. People expect it and are happy about it.
It took some time, but now I’ve found a conception to my note and I’m satisfied with it. The paper is fixed with crocheted flower, people can use it as a brooch later. I’ve got some good feedback about it.
