Thekla has been inspired by the brave girl Thekla from the children's book "Ritter Trenk", who rather wants to be a knight than a damsel of the castle. Of course, Thekla doesn't look like a girl living in the middle ages at all but like Thekla she doesn't care about cute dresses or learning how to embroider but rather prefers to ramble through the forests. She is wearing woolen cuffs and a hoodie sweater made of yellow boiled wool.
