Enjoy the birthday party and try not to eat too many cupcakes before you get there :-)
I once made 200 cupcakes with my daughter as a promotional freebie. The company logo as printed on rice paper and we put it on top of the icing. The mix was piped into the cases rather than spooned. They turned out great but I was sick of the sight of them by the time we finished. Enjoy your cakes and party.
Oh, I hope you ALL have so much fun at the party! The cakes will all be worth it :)
Everyone will certainly get a treat. Cupcakes just say "party" to me. Save one for yoursrlf for Tuesday-Monday you should rest, but Tuesday you'll be able to seat with a great cup of tea and cake and enjoy the fruits of your work.
I am sure it is going to be wonderful and Aunt Hettie is going to be thrilled! You will get back to normal -- eventually! Can't wait to see photos!
