JNCT, how Rhonda explained the process is the way I do it. I started with a 3 1/2" block on this one with 1 1/2" x 5" strips. I have done a couple others that I started with a bigger square and then increased the size of the strips accordingly. The Christmas runner I made with these blocks turned out awesome.
Have a great day! I have the day off so am starting a new quilt for our renters in MI who are getting married in May. Can't wait to see how it goes together.
