She makes a makeshift swimsuit out of the curtains.

As the two ladies continued to have their heated argument in the cottage about who should get to wear Dorothea's swimsuit, a loud voice suddenly entered the cottage through the window, calling for them directly.

"Hey, girls, are you done yet ?", said the voice, who belonged to none other than ferdinand, who was waiting for them to come and join the rest of their classmates on the beach.

"They are waiting for us out there, i need your swimsuit!", Petra said as she pleaded to Dorothea to let her have it.

"Sorry, but i just can't...", Dorothea replied to her, for she wasn't eager to disrobe in front of someone.

"Ok, but what do we do then ?", asked Petra to her. "Alright, Let me think...", she replied, upon which, her eyes looked around the cottage in search of something, until a certain pair of red curtains attracted her attention.

"I know what to do!", she exclamed as she grabbed the curtains, "Here, help me help you with this...", she said to Petra as she handed over to her a needle and some string.

"If that's you idea then...", Exclamed Petra, after which, the two girls began working with the curtains, until at last, they transformed them into a makeswift swimsuit, which Petra decided to wear.

"There, how do you feel ?", asked Dorothea to Petra regarding their work.

"It feels a little weird, but i'm fine...", replied Petra, for this was the first she had wore a swimsuit, and one made out of curtains stringed together even.

"Alright, i think we should go now then...", exclamed Dorothea relieved, upon which, she dragged the unsure Petra out of the Cottage by hand, as they finally decided that it was time to met up with the rest of their class.
