Such lovely quilts. I know your grandchildren will one day cherish these quilts. Your beautiful work must have been a source of healing for you in the loss of your son.
I remember my mother commenting that she never knew such pain until my brother died in Vietnam. I almost lost all 3 of my boys at one time or another, so can only partially understand how you must feel. You have my prayers for grace to sustain you. Your quilts will be such a gift to your grandchildren for many years to come. God Bless and keep quilting those beautiful quilts.
