My quilts are far from perfect, but have found that starching the fabric a minimum of 2 hours before using, then air drying or a few minutes in the drier, then ironing, helps me tremendously. Also when you press your blocks, make sure that you're PRESSING and not IRONING. Please don't get discouraged. We tend to be very critical of our own works, whereas whoever receives the quilt won't see the "mistakes" but instead, will be thrilled to receive the gift of a quilt.
