A book I found helpful was another Judith Mackenzie one, Teach Yourself Visually Handspinning. I was lucky enough to be loaned a copy as it's not one you need forever.
If you advertised for a secondhand copy on
Ravelry, I bet someone would sell you one.
Ditto hand cards, actually. I bought my first pair secondhand on Ravelry, because I wasn't sure what type I'd want, so figured if I bought 2nd hand I could sell on again if I didn't like them. Actually I have loved them and still have them.
One book I did buy and still refer to is Maggie Casey's Start Spinning: Everything You Need to Know to Make Great Yarn.
If she joins Ravelry, tell her to join the
Lovers of Ashford UK group. It's a really friendly helpful group, and her friends castlemilk and Fleecewife will be there, amongst others
We can point her at good vids for whatever she wants to learn next - the trouble with YouTube is there are so many vids out there, and they're not all giving good advice, so it's a good idea to get recommendations when she's starting.
Another place for really excellent videos is Interweave.com. You can buy and download videos on every aspect, and video versions of many of the top books are on there. Don't ever pay full price, get yourself on the mailing list and wait for a sale. They do up to 30% off very frequently, and occasionally go up to 50% and even 60% off.
As she'll be spinning mainly Shetland, I'd get her a dog comb and a simple flat cat/dog slicker brush to go with her hand cards, and that'll do her for starters.
