I knit, and crochet.
I buy general DK for 99p a ball, although it is getting more difficult to find.
Oh, I prefer 10 or 8 knitting needles, 10 for the ribbing. But for crocheting i have 3.50mm hook. Well, I have about 10 dotted aorund the house and will always find one if I need one.
However, must say the blankets I make are lovely. I made one to look like Thomas the tank for my partners lad.
