SunnyD, I know a lot of people who absolutely swear by a bit of knitting or crocheting in front of the TV before bed! Personally I get a bit absorbed in what I'm doing and stop listening to the TV, but it's a nice way to unwind after the day.

As to which I find easier... for me, it's definitely crocheting - knitting just gets me tied in knots! - but the friend who initially helped me get started says she can only knit and that crochet is beyond her (but she does the most stunning knitting so I suspect she's not too bothered

). I know others who do beautiful work in both, so I think it depends on just personal preferences and how much practice you put in.
As to your daughter's monkey, not long now right?
Lynndzee, I say go for it!
Charrowell, it's so lovely that you're carrying on what she taught you with her tools, I'm sure she'd be so proud of you.

And congratulations to your friend too!

I think it's a wonderful use of your nan's things.
