I came across a great article (here) on how to make your own charts. This woman says she likes charts so much, that she often converts written instructions to chart form. It's inspired me, and I'm fooling around with the idea of designing a program that lets you enter in text and produce a chart from it, so you can easily create a chart from an existing written pattern. It would also be great for designing your own pattern in chart form.
I've put up the poll to see how many people are into charts enough that they might use such a program!
I'm also doing this poll because I want to know if I should use charts in my pattern book.
