Salsa unless you have a relative or friend that can show you I wouldn't worry too much about lessons!
Knitting stuff is cheap ATM due to it being the end of season and wool and needles are on clearance. One of us in here can help you out if you get stuck with something but the knittinghelp site is awesome to get you started.

Thanks for your commets on the longies! The wool I knitted them with was hand dyed in various colours. Mostly turquoise and blue with a bit of orange and red and a few other colours that were made when they ran together. It was my first dying lesson I'm happy with the way it turned out but will do a few things differently next time because some of the colour didn't take which is why there are lighter parts.
