"Can someone please explain why everyone says I'm not supposed to tie knots in my crochet? I tie knots all the time, and my projects turn out fine. What am I missing?"
Fascinating question, Jessica. I can't speak for anyone else, but I'll give you my opinion.
When I was a kid, I used to tie knots in all my projects too. I didn't know any better. I was taught how to crochet, but wasn't taught many of the finer points, like how to change colors correctly. I figured many things out on my own.
When I was sixteen years old, I taught myself to knit using library books. The second knitting project I attempted was a multicolored fair isle shawl. I tied zillions of knots in that shawl. While I was knitting it, it didn't occur to me that the knots would all a) be visible on the back of the work, and b) be uncomfortable when I wore the shawl. I learned several important lessons there. After that experience, I vowed to break the knot-tying habit -- and I did.
So that's my story. I no longer tie knots, and I am happier with my work that way.
When I was a kid, I used to think that tying knots gave my project extra security. Nowadays, I prefer to leave extra-long tails of yarn, and I weave in the whole piece, or close to it. I cut off very little.
I'm sure Jessica isn't the only one who is curious about the reasoning behind the no knot-tying rule. Anyone else want to share their experiences?
While we're at it, let's do an anonymous poll. Spill it -- do you tie knots in your crochet?
