The Second Column of Squares - Step 1

Once you have finished your first column of squares, you build on that column. To do the first (bottom) square in the column you have to cast on 22 stitches and then pickup 23 stitches on the side of square #1. In the picture, Square #1 is the dark blue and the new square is the lighter blue.

This photo shows 22 stitches cast on the needle and the side of square #1 where you will pick up the stitches.
