I think that's it. She's super picky and I think the worlds hardest to shop for Mom ever. Any ideas folks?

Make something meaningful and of sentimental value.

How about cleaning the house, washing dishes, doing laundry, making lunch/brunch/dinner?

I do the dishes everyday already, she wouldn't let me touch her laundry, cooking she wouldn't like because she hates when people cook. The only thing she may appreciate is cleaning. Thanks for that idea.

How about a card with an "anything you want" coupon in it. She can use it for whatever she wants...

If you ask her, what would she say?

Wash her car, vacuum the inside? Wash or dry clean curtains/drapes? (I need my bathroom curtains and shower curtain laundered.) "Big" cleaning like washing bathroom walls or cleaning out bathroom cabinets or cleaning out and straightening kitchen drawers?
