well I think you know now, so here I give you another, just for you and to the replieres of your question :)
Waaaaay back when, in the very beginning this was posted by the site Owner: : "Cuteembroidery.com is conducting testing at this time. Flowers will be used to provide new and additional benefits to users of Cuteembroidery.com."
This is what I added much later (a couple of years) and it still fits.
They seem to be a good thing to be collecting because my bouquet surely does smell good and look pretty. As for how you get them, you get one each day (once every 24 hour period) that you visit the site. We can now get them from others on this area of the site, and also in response to questions and answers and Cudo's for projects. And that's the short answer! I'm sending you one now. ;)
So, the test is over and we just kind of took over giving flowers as a way of welcoming and saying I like what you did/ said / made, etc. So Welcome to Cute Embroidery and I'm so glad that you are here.;)
Welcome to Cute!
Flowers are like a hug. Often giving someone a flower is called "watering their garden" There is no prize for the most flowers it is just an easy way to say something you would say to a friend when giving them a hug or to someone when you first meet.
If I read the question I give a flower. The more questions you ask or answer, the more flowers you will receive. If you post in projects or in the DBC (Designs By Cuties) you will also receive flowers.
To mark the question asked, you click the grey mark between the picture and their name. It turns orange like the flower.
As much as I can tell they are to say thank you for asking a question or posting an answer. Also to mark that you have read the Q&A. Or that you like a project. I hope that I am right, I am fairly new, too.
