I was wondering if you wanted a pattern or size of the different quilts. Are you looking to make a full-size crib quilt or preemie quilts?
If for a preemie, a 24x24 or 24x30 is more than sufficient. If its a possibility that they could be in the hospital for a time, this is a very nice option. The parents (I know this sounds weird) would rub the quilt on themselves to get their scent on it and that way the babies become familiar with the parents scent and it comforts them.
