Mitered Squares cast on the full amount of stitches for two sides of the square ie cast on 32 stitches for 16 stitches per side and then you decrease on both sides of a center marker.
There are also options for decreasing two stitches at once instead of on each side of a marker but for All Squared Up, the pattern uses a center marker and then decreases on both sides.
Mitered Squares can be used in a variety of ways. All Squared Up uses them a the bottom of the shawl for binding off, Scrapbook Cowl uses only mitered squares to create the body of the cowl.
Mitered Squares really are a fascinating and fun knitting technique that is simple to knit and a great way to explore color. I can't wait to see the color groups knitters come up with for All Squared Up!
