Question concerning Sleeping Beauty

Merryweather said that Flora couldn't sew, and Fauna couldn't cook. Merryweather also said that she's never baked a fancy cake before after Flora said they weren't using wands because she had assumed that she was making the cake. She also knew that tsp meant teaspoon, so it's obvious that Merryweather was the cook out of the three.

As for the clothes, it's the assumption that the fairies just switched jobs, and that Fauna was the one who did the sewing.

Basically Flora and Fauna wanted to try something something new for Aurora's birthday, before Aurora went back to the castle.
