Quick and easy to crochet! You could easily whip one up in a day or maybe 2 evenings.
I am sure she will love it sitting next to her chair filled with wool. She loves knitting!
These are quite a decent size too. I am now in the process of making myself one while I write up a pattern. I have found lots online, I mixed a few patterns to make it simpler (crochet for dummies, with lots of links for help).... I am no expert at crocheting that's for sure, but I am very pleased with how this turned out.
