I am so sorry to hear about your sister. A free pattern from Red Rooster fabrics is called Heart and Soul (it is one pg 5 or 6 of their retired patterns). I have done this quilt a few times, twice as a baby quilt in brights and three times in soft pastels for adults. The last one I made was for a friend who was going through chemo and it was done in puples and violets because that was her favorite colours.
