* Take your time with learning new techniques. You don't want to frustrate yourself.
* The internet is a wonderful tool, but if you get stuck, always ask another knitter. Having someone show you versus reading the diagrams in a book or on a webpage is very helpful.
* Ravelry.com is an amazing resource. You can ask for help in your local groups, find local yarn stores or locally made fiber, tonnes of free patterns or amazing ones sold by other knitters....or engage in various discussions with people from across the world. Personally, I don't know what I would do without it.
* There are different methods and styles of knitting. Every knitter has found their own method that works for them. Just because it looks different, doesn't mean it's wrong. As long as you get the same results, its all gravy.
* crochet hooks and safety pins can be invaluable tools when learning how to knit. Especially to help count rows, pick up dropped stitches, or to help hold something in place. (I still use both)
* Stitch and row counters can be a lifesaver.
* Learn your core basic stitches to make learning other stitches and techniques easier. Knit, purl, cast on, cast off, increase, decrease. Once you learn these, you can make almost anything.
* There are all sorts of knitting needles out there. Plastic, Wood, Bamboo, Metals. Other knitters have insisted that bamboo helps with wrist problems. Plastic can break if it gets cold cause it gets brittle (also with age), but this also depends on the manufacturer. Aluminum is light, but I find in thinner gauges it can bend fairly easily.
* It will take some time to get the tension right. I used to knit super duper tight. My sister knits so tight she chipped all the anodization off my needles. Some people knit loose and it causes huge gaps. Keep practicing....as they say practice makes perfect.
* If you get frustrated, do something else for a little bit, then come back to it.
* Be careful how you store your projects and needles. I've stabbed myself with my double pointed needles on multiple occasions. Needle point protectors are wonderful things to have in your stash. (i have red and green sock shaped needle protectors in my collection of knitting tools)
*Setting goals for yourself is always a good thing. Just make sure they are YOUR goals.
