I am not as far along in my knitting as a lot of the knitters on this blog, but I learned early that a copy of a chart of yarn weights, needle sizes with conversion of US and UK added. I also have a copy of abbreviations. However, once in a while I run across one not on my list. I just add it on. I am not being critical of anyone, but these three list has proved very helpful to me.
I have done the same and keep it in favourites as well as printing off a copy - with the internet being so international and folks from all over the world posting patterns with terms we aren't familiar with I find it an essential tool.
