I see the makings of what we call "Come Help Mom" parties. My daughter and a few friends come down to help,and after everyone has worked so hard, I have some kind of relaxing dinner food, (anything from Taco Bell, to home made soups served in big mugs. (It is nice especially in the winter, with hot cocoa mugs also.) Nice to sit and catch up on the everyday stuff.
When my daughter and her friends come to 'help out', I am not much help, but I can be the "gofer" and have one of her favorite meals ready, when they are done.
I just love it when my house is full of young people and the noise they bring, almost as much as I love the return of quiet when they return home.
*And you, with a sewing room, (to fill) in the bargain, sounds like heaven in the making! Have fun. :-)
