I have hand quilted one quilt in my life.
A wedding quilt for our oldest son, and I decided to just do a straight line.
After doing a straight line through the queen sized quilt, I understood why people starting doing curves and different things, and I think that is when I decided to learn machine quilting.
You will see ....
you will start simple, then you will start branching out, then you will start experimenting ... it is a process <g> we all go through it to one degree or another, and it is a necessary part of becoming proficient in anything.
