I took up knitting when pregnant with ds, who turns eight next week. I now have two large storage cube units full of wool, a house full of mostly completed knitted projects and about 100 sets of knitting needles in different lengths, sizes, straight, circular, dpn, sock needles etc etc. I have 5 projects on the go and about 10 more in my 'to make' list. Its a slippery slope, I tell you!
Charity shops and ebay are fab for knitting needles, and wool. Ravelry.com is the first place I go to for patterns, also a lot of the wool sellers and manufacturers have their own patterns online too. I often search youtube for unfamiliar stitches and there are lots of lovely helpful videos out there.
My local wool shop is independently run, and also has a stitch and natter group which is a lovely bunch of people, very willing to advise. If you have a local independent wool seller, go have a chat with them, chances are they are connected to a secret underground network of lovely knitters and crocheters!
My top tip is if you are making something for someone, make a note of the laundry instructions on the wool band, and pass that info on when you pass on the gift. Nothing worse than working hard on something made of pure wool, only for the recipient to unknowingly chuck it in the tumble dryer.
Enjoy your lovely new hobby!
