[B]"P1, k tbl, p1, k tbl..."
[/B]Above is what it says for the stripes with your working the cable pattern at the end. What you could do is add another "p1, ktbl" so it would read -
"p1, ktbl, p1, k tbl, p1, ktbl..."
You could also add some extra purls in there if that wouldn't be wide enough...
"p2 ktbl, p2, k tbl, p2, ktbl..."
It will change the look of the shawl a little, but it would still look nice.
