We did it! The breakfast was very well received. I forgot to take an early photo, but this shows the center of the table after the first wave came through. I ended up getting Walmart $1/yd. fabric for the 9 foot long table--an ice blue microfiber with a heavy drape and excellent wipe-ability. Is that a word? Well worth the $3.47 it cost at the last minute.
I spent $100. I could have saved more by not buying as much fruit (uneaten) and making less fruit tea, or a cheaper version of powdered spice tea. The not so frugal part of the baking adventure: I killed my oven. At least the electronic control part. That's why my muffins were baking so strangely. The heat cycled on and off between two elements instead of evenly. Who knows if this experiment was too much for the home oven, or if this was the last straw for a pre-existing condition.
Now that everything's cleaned and put away, this girl is taking a nap. We have basketball tonight!
