I know it has been awhile since this thread has been live... but I spoke in personal with several staff members at Craftsy this month.
During the process, I learned that they place value on the size of your following. That said, it is important that we grow our following as designers.
Please post a link to your shop. This way, we can all become fans.
Another tip/trick is to add projects. In the last two plus weeks, I have added 3 projects and have noticed a jump in my following and my sales.
Here is a link to my shop.
