When I started quilting again after a 10 year break I spent over and a hour just sewing together short 2.5" strips and measuring the result until I was sure I had the 1/4" seam process back in memory. I'd just recommend several iterations of practicing sewing a set of short strips like was mentioned above. I like to sew 3 or 4 strips together. If using 4 short (6") strips that gives you 3 seams. If your 1/4" if off each seam increases the problem. So with 3 seams you can more easily tell if you have it right.
