I don't have enough of another flannel in coordinated colors. I like the idea of a pieced design element on the back of some quilts, but for this I just want a soft, smooth as-seamless-as-possible all over backing. I'm also going to piece the extra section along the side so that no seams are near her port ( she can tuck the seamed side behind her on her "good" side when she's sitting up. I am going to suggest that her friends and family can sign their names on the flannel side, which will be closest to her heart.
