Welcome from southern California! You will do fine. My first quilts were hand pieced together and the trick is to keep a full quarter inch seem, keep the stitches small and regular. With light fabric I would draw a sewing line on with a pencil and on dark fabric I use 1/4 inch masking tape. It was easy to sew next to and can be used several times over. It used to be that you can buy the tape at a hardware store, they would cut it for you. I have not bought any in a long time so not sure if they still do it.
