I love this app!

Great simple app that is easy to use and very clear. No bugs so far. To find a knot guide at Barnes and Noble it is going to cost you around $4.99-$9.99, so this app at $2.99 is a great deal. If youre anything like me, and are terrible at making knots, this app is for you! Concise and clear instructions.
