I know how you feel! I do not like to wash and press fabric before making a quilt. Most of the time I buy high quality, high thread count fabric so the shrinkage is very minimal but when I buy cheaper fabric I've learned the hard way like you....it pays to preshrink the fabric.
Don't toss out the fabric...save the scraps for a scrap quilt someday. What is the saying? When life throws you scrap...make a quilt!
