|I mean LOOK at that knitting. So pretty.|
But, you could also consider that a signed copy of her book "Knitting Ganseys:"
1) Is awesome.
2) Was out of print for a while, so you may not have seen how awesome it is.
3) Pretty much costs $30 anyway.
There are a bunch of other things you can choose as your reward for helping her out, but I'm going with the book...
