I don't wash my fabrics first I make my quilt layer it and quilt it. Then I put binding on after it is done I wash it and yes you will get the crinkly effect. I use color catchers one or two depending on the colors in the quilt.
I did a small table runner once quilted it sew the outside all around the outside washed it and it was really crinkly then I added the border. There really are No quilt police. Enjoy
