Honeycomb (pattern)

This mid-scale blackwork pattern is made up of a series of hexagons with a square inside each one. Its honeycomb effect makes it good for natural designs.

Method
Start with a straight horizontal stitch over two threads of fabric.
Complete a column with clusters of three straight stitches with a space of two fabric threads between each cluster.
Work up and down to produce more columns to fill the space; each column should be two fabric threads apart and the clusters offset from the columns either side.
Work across the shape again using vertical stitches over two threads to bridge the gaps and make squares.
Finally complete the pattern by joining the single horizontal stitches with a diagonal stitch over two intersections of the fabric.
