I use handwriting script fonts all the time for my design projects. They are a big hit due to their lovely feminine fluid flow of the letters. There is a huge database of such modern calligraphy script fonts out there but i find myself drawn to these favorite eight fonts. The best part is that they are free to download!
I love these fonts!
