I need your good ideas

Finding the perfect birthday gift is often difficult.

My stepmother's 60th birthday is coming up. I don't have any good ideas. Do you?

She's very active and sporty, but alas, she works in a shop selling sports gear, so that's out of the question. She likes reading, but doesn't have the time really. There's always DVDs, but with a special birthday it seems a bit lame - and anyway, I haven't got a brilliant DVD idea. She likes arthouse stuff, preferably sad and romantic.
She isn't big on makeup and stuff like that and I highly suspect that her friends are giving her a giftcard for some sort of spa/sauna place.

I'm a bit at a loss.

Also, she's got a twin, so I need something for her sister, too.

Come on, help me please!
