## Basic 3x2 Knot

#### How to add Breaklines

There's an invisible grid in the pattern above, where the coordinates range from x=0 on the left to x=6 at the right, and from y=0 at the top to y=4 at the bottom. For example, the top right corner is at (6,0) and the point just inside that corner is at (5,1).
To add a breakline, figure out the x and y coordinates of the breakline, and enter them in the Breakline Coordinates box, in the form of **x, y, x, y**.
For example, to add breaklines just inside the left and right sides of the pattern, use

**1,1,1,3**

**5,1,5,3**

Or, try this:

**1,3,3,3,3,1,5,1**

*Special Note: Each breakline must consist of either all odd numbers, or all even numbers.*

If all this is too confusing to deal with, take a look at Constructing a Celtic Knot by Marc Wallace. The "Inside Borders" he describes are what I call Breaklines.
His example is a 3x3 knot with breaklines as follows:

**1,1, 3,1**

**4,2, 4,4**

**1,3, 1,5, 3,5**

He has 4x4 and 5x5 examples with the breaklines shown on a grid. You'll have to figure out the coordinates to get them to work here.
