That is truly adorable. Even better that your granddaughter helped you create it! What a cute idea!
I have my granddaughter coming over next weekend and we are going to make a container fairy garden. She asked me last time she visited and we didn't have enough time to start it then, but I plan to do so when she visits in a week. And of course, she will get to take it home to keep in HER yard! My yard is getting pretty filled up, so this will give her something to enjoy at her own home.
