Last night, while reading one of my knitting books, I noticed that instead of making my knit stitches in the front leg of the previous stitch, I make them into the back loop. In other words, I make what is called a twisted knit stitch where I should be making regular ones. I've already finished two sweaters this way and am in the middle of making knitty's Cleo top right now, all wrong
What exactly is the difference in how the finished stitches look, depending on whether they're twisted or not? How can this influence a pattern?
