Thank you for your reply PaperPrincess. Since this is my first quilt, I didn't realize that I should have squared up my blocks before sewing on the sashing. I wondered why when I cut the sashing strips to the correct size, why some of them ended up about 1" too long. Maybe it was stretching as those were cut on the crossgrain and pieced together. Something I don't enjoy doing. I can never get my strips look perfect all the time. That is a good idea about cutting your borders slightly wider. Do you do that to make sure that once it's square that your borders will be the same size?
