About 6 years ago a friend of mine decided to teach herself how to knit. It was the trendy thing to do at the time (that's not necessarily why she did it) so I decided it would be a good time to try it out.
At first, I had great difficulty. I am left handed and I couldn't decide if I wanted to knit left handed and have to spend time reversing every pattern written or if I wanted to train my hands to knit right handed. After a few very frustrating attempts at left handed knitting, I gave up and began to teach myself to knit right handed. As such, I do knit slower than most people I know and I almost always have to watch what I am knitting. I don't mind, because knitting has become my form of meditation.
There were a few years that I barely touched my needles so that every time I tried to knit I had to relearn what I was doing. Then one day, I don't even remember when, I found myself addicted to yarn. At the start of the addiction I didn't really know fiber very well. I bought because of color or texture not really understanding how much of a particular yarn I would need for a project or if it was appropriate for the project. As a result, I have numerous balls of yarn that may never be used, but are pretty to look at. I think this is a fairly common problem for beginning yarnaholics.
Now, several years later, I am selective about my fiber purchases. However, as hard as I try to tell myself that I shouldn't buy yarn unless I have a specific project in mind, it just won't stick. I do make sure that I buy enough for some project, just not a specific project all the time. I have all my yarn displayed in cubby holes and I look at it all the time.
I love my yarn almost as much as I love my children. :)
