Traci, you mention Madisyn, but no mention of her premature birth or death, so the "in memory of Madysin" may confuse people.

I think a brief sentence, after "my sister carrying a girl," and before the "in memory of" part that states simply that "sadly, Madysin was born X weeks premature, and did not survive. In memory and honor of her, and premies everywhere, I am creating these quilts."

I had two siblings who only lived a day each, and other families may be comforted by the thought that they are not alone in their grief. Families whose babies don't make it are often callously told, "Oh, well, it's not like you really got to know X, you can have another." without acknowledging the many months the mother spent growing and caring for new life inside her.

Just my two cents.
