As far as choosing fabrics, you will want colors that you like working with, or it could get boring very quickly. You must be fair to yourself.
Also, if you are selling them you want to consider cost to you.
I recently did a lot of figuring about materials, thread, batting, electricity for the machine and the light, and my time (which I find to be precious). I tried to include everything as though it were a business. A real business would account for all of these things, even wear and tear on the machine. After an hour, I came up with a standard. Nineteen cents a square inch. That may not sound like much, but a moderate sized lap quilt of 45 x38 would be $324.90.
