This is the first in a series of blog posts exploring Celtic knot crosses. “2 by” refers to the fact that the arms of these knots are two sections wide, and an increasing number of sections long. A later blog post will introduce breaks in these knots.

Each example will display a line drawing of the knotted cross, and a colored version. The colored version features three basic shapes (corners, curves, and bars) with a bit of space added, and the colors illustrate how many strands are in each knot.

**4 by 4 knotted cross:** eight corners, eight bars; four colors.

**4 by 5 knotted cross:** eight corners, two curves, nine bars; three colors.
