Somehow, app launches drive me to overuse the exclamation point!!!
I hope you'll try Knittrick and let me know what you think. I wish I could spend all day tweaking the website and adding tutorials and all that, but I have to go to class! I'll be back this evening... I hope. :)
P.S. Knittrick is priced at $4.99 USD. Less than the price of most patterns or balls of yarn! Knittrick cuts out a lot of tedious calculator button presses and saves you from getting confused in the process (which is always a problem for me, I don't know about you).
