This Cakes & Candles pattern is perfect for a 1 ball shawl, but it is also easily adjustable to a full size shawl by using 3 balls of yarn. The border is already done for you just by finishing off on a shells and candles row. Can easily be made with worsted weight size 4 thickness yarn and a 6.0mm hook.
This is a wonderful pattern--fast and super easy to follow. The shawl can be casual or sophisticated depending on the yarn choice. Christa does marvelous and fun tutorials! Check them out if you haven't.
