ColourSpun In Stitches - Mitred Square

This is the most basic square used in modular knitting. Each square shape is knit by casting on an odd number of stitches then decreasing 2 stitches in the middle of every 2nd (wrong side) row until you run out of stitches.
The size of each square is determined by the number of stitches cast on (and/or picked up) in the beginning. This will always be an odd number of stitches as follows: X +1 + X.
Squares can be knit individually and then stitched together or knit onto each other by picking up X number of stitches and then casting on X + 1
