I used to sew clothes for myself and my children, the biggest difference is the seam allowance. It is 1/4 inch instead of the 5/8 inch you use in sewing clothes and you don't have to press the seams to one side, do whatever fits the situation. Be sure you know the difference between ironing (like clothes moving the iron across) and pressing where you lift up the iron. Some quilters like steam and some don't. Good idea to take a beginning class at local quilt shop if possible but remember everyone has an opinion on how to quilt. So don't get discouraged.
