DH's grandmother's birthday is coming up and I dread it EVERY YEAR. I don't know what she wants. The gifts we always get her have been a hit though. We've already done: robes, slippers, throw blankets, lotions....
She doesn't go out much and also doesn't eat much...but she does knit!

So, I got her this upholstered storage chest that she can use as a footstool while knitting, but it opens too so I want to fill it with knitting supplies.
What knitting supplies would a knitting person want?
Please help. I want to get 'the good stuff'
