I prefer charts for every type of knitting rather than the line-by-line written instructions. I purchased a pdf scarf pattern a few years ago, and I appalled to find only written, line-by-line instructions! It was quite a complex "leaves" pattern design, and should have had charts included. I tossed the whole thing aside. About a year later, the designer finally coughed up charts!
You'll love working from charts if you give it half a chance, I promise!
