you may have faster progress by keeping her in a very large crate (ex. 4' long dog crate) and working with her in it. I did that with Domino, a stray in my neighborhood who was terrified of me. I trapped her and kept her in a large dog crate. After sitting in the crate with her for several weeks and teaching her I wouldn't hurt her, I let her out. She pretty much kept to the basement because of my other cats.

Sadly, just as she was starting to come upstairs and to me for meals, she became ill. During surgery to explore a cystic mass, they discovered it was inoperable liver cancer; I let her cross the Rainbow Bridge.

Other 'scaredy cats' I have, Trill and Emmy, eventually learned that good scritches come to those who lie down near me. So even if a couple of them dislike losing their gravity (do NOT pick me up, thank you!), they will get on the couch or bed next to me to cuddle and be petted.
