Sea Foam Shawl (part 3)

This shawl has a garter stitch border of 3 stitches, a central single stocking stitch, and these are separated by lines of yarn over holes. The shawl starts with stocking stitch panels. 

After the first ball of yarn has been knitted up, the stocking stitch pattern continues until the total number of stitches is a multiple of 36, plus an additional 7 stitch. The pattern then switches to a modified 'Old Shale' design. Old Shale is worked over 18 sts, and 4 rows. This modified Old Shale is worked over 18sts and 2 rows. 

The Shawl is finished with 6 rows of garter stitch, and ends with a stretchy lace cast off.
