The Ariana shawl is a top down crochet shawl meaning that you chain a long chain to begin with which will be the top of your shawl and you crochet row by row across the width of the shawl and work the whole pattern downwards like that which will give you a lovely rectangle shawl, it is as easy as that so you don't have to worry about any increasing and decreasing which can get complicated sometimes.
