Hundreds of Happy Meals on each greenhouse.
I really do tell my wife that I made such and such number of Happy Meals. By the way, we haven't been inside a McDonald's in probably 30 years (or takeout for that matter).
My wife loves that I have a hobby that not only gives me something to do but one that allows her to have her own quiet-time in her art studio. Needless to say, though I am often busier than I would like, what I do is a labor of love. Profit has never been an important part of the equation, if you know what I mean.
