I never use steam while piecing. I have found in the classes that I teach, that when students spray or steam their fabric, it warps. Try this experiment... lay out a half yard piece of fabric, and steam or spray it with water, then iron it. Some people can press it without warping it, and some people can't. I teach that you can use water or steam before you cut the pieces, but after you cut, the water will re-shape the fabric. That has been my experience, any way.
Also... I have watched with horror as I spritz a piece of excellent quality Moda fabric and watch it shrink up as I pass my iron over it. Good reason to steam press BEFORE you cut.
