I would like to start crocheting, what type of yarn is easiest to start with? and any tips?

There is not exactly any yarn better than others as far as brand names. I think a thicker yarn is easier than a thin yarn fo a beginner. Start by doing something simple. I think a granny square is fairly simple. You could do a lap robe with it. Work with a cheap yarn to get the basics down and then go on to a project like the lap robe. There are tutorials on line that can help you get started
