Maybe you could get your Mom and Aunt to help you and Granny redo her sewing room. You guys could have such a great time spending the day being together and just chit-chatting about old times and everything as you do this project. Your Mom and Aunt could fold the fabric and sort it by colors while you and Granny organized the room. If the room is to small for everyone to be in it at once, you could always fold and sort the fabric in another room. Good luck and I know Granny will think this is one of the greatest gifts ever.
