Modular and Mitred Square Knitting
Modular knitting builds large pieces from small interlocking modules. The most common module is the mitred square: a square knit from corner to corner with a centred decrease at the centre. Squares are joined by picking up stitches along the edges.

Basic mitred square
Cast on twice the side length plus one stitch. Place a marker in the centre. On every other row, work a centred double decrease at the marker. Continue until 1 stitch remains. Bind off.
Joining squares
Pick up stitches along the edge of one square to start the next. The new square is connected to the existing one by the picked-up edge — no seaming required.

Multi-colour effects
Use a different colour for each square (or each round of squares) for a vibrant patchwork effect. Garter-stitch mitres with bold contrasting colours are a classic mitred-square aesthetic.
Best uses
Blankets (the most common modular project). Tote bags assembled from squares. Modular shawls and scarves. Any project where the construction itself is part of the design.

Tips
- Use garter stitch for the most forgiving mitred squares.
- Plan the colour sequence before starting — it cannot be easily changed mid-project.
- Block each square or section before joining for the cleanest assembly.
In depth
Modular knitting allows huge projects to be built from small portable modules. The combination of small project pieces (good for travel) and dramatic finished result (large blankets, throws) has kept modular knitting popular for decades.
