They'll love it. What scent did you use?
Snappy, I love the idea of the grab bag. I don't think that's silly at all. I remember the first house I bought. The people had had their children in that house and while the kids were still relatively young and they needed more space, all their family memories were there. The lady was broken up to be leaving it and I remember her tearfully hugging me at closing and asking me to take good care of the house. Thankfully she did not know I'm a slob and thankfully I was married at the time to someone very good at keeping things neat, so the house was kept up very nicely. When my ex moved out of the house, he hid a little package my son had made for the house in the storage space in the attic, tucked away for come future person to possibly find. It's all the little stuff we do that makes things good, like making soap for the new owner or the grab bag or the hidden treasures.
