Crochet lace edgings by Nilza Souza, from her facebook photo album "Barrados". I like the all-white on top best (unfortunately it does not come with a chart), but the chart given for the blue and white in the middle is similar enough to be taken as a general guide.
Crocheted Angels and bells not many patterns, but good pictures if you are talented.
