It's about consistency - put her up on a table/ counter/ ironing board every day for a few minutes and brush her all over. If needs be put a harness on her and hold on this with one hand while you brush her using the other. May be easier to keep her stationary this way if you're worried about her jumping off. Also get her to sit on the table and administer lots of cuddles, tell her she's a good girl and give her a treat once she's let you brush her. Pick up each foot, lift her tail, pick up ears, etc. Treat, cuddles. Repeat every day. She will learn the table is a nice place to be. My two boys particularly, ask to get onto the grooming table. It's a special bonding time for us.
