Lantern Stitch Rectangular Shawl

This rectangular shawl turned out to be much wider than I expected. The rows went across the long portion of the shawl. I made sure to have plenty of stitches, since I thought the stitch would stretch down. It did not. Instead it stretched across the row.

Here is the shawl as seen from the back.
