I would use what you have..it sounds like you MIL is trying to do a loving gesture for her mom and trusts you to help her out...I would say that she is showing her love to you too by trusting you do this project...I just had to put my dd in a nursing home not easy on the heart ..we set up her room just like her bedroom so she would feel more at home and comfortable..I think it is very loving of your mil to want to do something like this for her mom...blessings
