Upon meeting with Annabella for dyeing lessons Kira learned?

Kira learns how to cultivate and utilize various plants to produce a variety of different colored dyes. These are the dyes that are necessary for her to make the thread she needs to maintain the robe. When Kira asks Annabella if she can make blue thread, Annabella says doesn't have the plants that are required to make the dye. She then tells Kira about people who live far down the old path that leads away from her home. They have the means to make blue.
