Paulaque, glad you aunt's treatment is going along and going well so far. Good for her and for you for being so close to her.
I have to admit, I'm a big Addi Turbo fan myself even though I'm a loose knitter. I went a few rounds with metal dpns however and they go the best of me. They kept shooting out of my knitting like the ice spear out of the gutter in Christmas Vacation.
i switched to bamboo dpns.
