What type of work is Corrie assigned to do after her visit to the eye doctor? Why is this a blessing?

Can you include the chapter please?

i do not know the chapter

Because of Corrie’s eye appointment, she has no work detail for that week and makes her way to the knitting brigade. The time in the knitting barracks is the best Corrie experiences in Ravensbruck, with relatively easy work and proximity to her sister. Moreover, Betsie and Corrie have a chance to share the gospel, minister to the neighboring knitters, and pray for healing in Germany, Europe and the world. They pray even pray for the guards in their camp. After the war, the sisters plan to open a home for people damaged by the horrors of concentration camps.
