From Stitch 'N Bitch Crochet: The Happy Hooker:



Made in mouthwatering linen, which softens with each wash and drapes beautifully, Blissful can carry you through the stickiest summer day with elegance.  (Of course, you can substitute with any other summer-weight yarn).  Pair it with a slim white skirt for uptown flair, or with jeans for downtown funk.  If you’re a tad shy, wear it over a silky camisole and let the colors peek through the lace pattern.  Besides providing vital aeration, the wave stitch is a delight for the crocheting hand:  easy to remember and works up very fast.  Instant gratification was never more gratifying. 



Note on gauge:  With larger hook, 19 stitches = 4.5 inches; 5 rows = 4 inches in wave pattern.
