I used to do ATW the traditional way untill I got Eleanor Burns "Quick Trips". I will never make it the old way ever again. You could easily adjust the size of your strips to be whatever size you want and then continue with her method. I love her method and ATW is one of my favorite patterns. Don't give up. I have resized this quilt down to baby size and up to King. Go for it! PS> I agree not to go to small on your block size. My favorite is 3.5 for a 3" finish.
