I hand quilt all my quilts. I have gotten addicted to Baptist Fan and it is easy! I don't use a template. Just start an arc in the bottom corner and expand and expand -a finger's width apart . I use 7 rounds and then start another one going at an angle - go seven and then in between the first two. It is easy and fun.
I am sure there are tutorials online, if my directons were clear as mud.
I also really love diagonal cross-hatching, especially for appliqued quilts leaving the applique "puffy" and unquilted.
Around the border, use leaves or hearts or triangles- again just meandering lines with a cardboard template.
Good luck.
