Hi
Card making is good, can be expensive, but can be cheap too if you shop around. ebay is fab for stuff
Dolls house, expensive, my daughter has one, and once it was done up, after only 2 weeks, it doesnt get touched now.
Cross stitching good, not too expensive and can be addictive.
Can I make another suggestion tho. Ive just started a 'wii fit challenge anyone?' thread, obviously you need a wii and wii fit, but the aim is to try and beat the current top scoring person for any of the games/excersises.
This has a real plus side, cos it will aid your loss.
