While browsing around, I came upon a new chart maker! Knitting Chart Maker by Jacquie. The best part, it is free! I haven't tried it extensively but so far what I see me likes. Go check it out.
I have a charting software in my computer but this one you can access from anywhere as long as you have internet access, perfect for those times when you go on a trip and can't take your desktop with you. Thank you Jacquie for providing this program for all of us.
