This is a revised pattern I originally wrote 8 years ago. It now has better pictures, a help video, and all stitches are picked up from the front side of your work. The pattern requires a lot of precision, and so I included lots of helpful hints to knit this beautiful work of art.

32” Circular needles are needed for large number of stitches.
There is an instructional video to help with picking up stitches along the mitered square edges.
