Applying make-up with shaky hands

I don't wear a lot of make-up but the colour of my eyebrows is so washed out now that I've been using a pencil, powder and even sometimes brow dye to make me look less like Miss Havisham. But now, at 77, my hands are starting to get quite shaky and I dread over-doing things with a thick wobbly brow line (I hate the current trend of scrubbing on a couple of dead-caterpillar shapes like a 4-year-old let loose with a black crayon). Anybody else have a similar difficulty and, if so, any tips on how to deal with it (other than resigning myself to looking as though I've escaped from a morgue)?
