Well I'm going to come from the daughters' point of view. You know your daughters-will both of them appreciate the value the end product as you want them to? If you want these passed down be sure you make that clear to them. Also do they have children? How to pass the items on? I know you have 2 pieces, but one is made by their grandmother, the other by her sister. Did or do they know your aunt? Will both pieces be valued equally or will one daughter feel slighted that she did not receive something from her grandmother? If these are possibilities I would say you should find a way to make two projects from each piece, unless you can somehow incorporate some of each of the originals into 2 new pieces. Family dynamics can be tricky and it's better to be totally honest with yourself concerning these issues now in the project decision making process than dealing with unexpected reactions down the road.JMHO
