Sega - That is so awesome that you will be getting a guide dog. They amaze me with their talents and loyalty.
K - Sorry to hear you are having issues. As my mom always says - This, too, shall pass. Meanwhile I'm sure it's not easy, so consider yourself added to the prayer list.
Lori - What a horrible diagnosis. Although, I have a friend who had it, and she has now overcome it. Not sure how, but it can be done. Good luck and I'm so sorry you are in pain.
Using acrylic yarn would work good for doilies. My mom made one that ruffled and I keep a vase of flowers on it. Love it.
