Yes, sounds like you will need to start over. Take 3 of your 6" squares and "sandwich them together". Then sew an X across the "sandwich". Then sew the "sandwiches together using a 1/2" seam, making a row of squares as wide as you want your quilt. Then sew each row together for the length of your quilt. Then sew 1/2" around the outer border of your quilt, as this will be ragged also. So when you finish, one side will be smooth, and the other side will show the ragged edges. Then clip the ragged edges approx. every 1/8-1/4". Then wash and then dry with a towel or two to help the ragging process. I hope this makes sense.
