I'm Cindy (called knitcindy here) and I'm a 50-ish mom of 4 from the USA. I have ALWAYS wanted to visit Ireland since my dad's parents were both born there.
I want to recommend a book to get for your cousin. It's called "Knitting: Learn to Knit Six Great Projects" by Klutz publishers. It explains how to knit VERY simply and then has 6 projects for her to try.
A dvd she could watch is: "The Art of Knitting 4 Kids". I've gotten both the dvd and the book at the local library. VERY simple to understand and helpful. This has some easy projects as well.
