This is a wonderful quilling video from My Quilling Nest. She shows you how to create a fringed quilled flower with and without a center. Please note that she is using 24" quilling paper cut 3/8" wide, but you can certainly modify that and use 12" papers cut to all different widths, depending on the size you want your completed flower to be.
Quilling tools are available at all major craft stores. I use CTMH's new tweezers for quilling, since I pretty much only quill flowers.
