Hi, I have recently started knitting - nothing fancy, just practicing at the moment with different stitches and techniques. On the advice of the lady in the local wool shop, I bought some chunky yarn and some 8mm plastic needles just to get started. However, I would like to try a couple of projects from this book and I need to buy some more needles and yarn. My question is, what is the best length of needle to buy? I was looking at 33cm ones on Amazon as one of the projects is a baby blanket (casting on 70 stitches with extra fine merino) and I assume these will be long enough. Is it harder to knit with longer needles or does it not make much difference. I don't want to shell out buy lots of needles in different sizes and lengths until I'm a bit more proficient.
Also, am finding that the end stitches of my practice squares seem to be looser than the rest. How can I get these to be tighter?
Thanks for any advice
