in the back of the quilt top lays down neatly. this will result in a block that is neatly done. that makes it easier to join blocks together to create the overall quilt. in pressing, a dry iron (no steam) is recommended. steam can cause the fabric to stretch, which can lead to problems. if you need steam to tame fabric, spray the block with a fine mist as you go rather than using the steam feature on your iron. it is easier to control that way.
once you are comfortable with how to cut fabric and join it into a patchwork block, there are hundreds upon hundreds of design possibilities!
