According to the Free Dictionary, a jabot is a frill or ruffle on the breast or throat of a garment, originally to hide the closure of a shirt. (Which, depending upon the level of your sewing skills, can be a downright good idea). I'm generally not into a ruffled neckline, as it find it irritating, however, the jabot is an entire different story.
I came across this particular jabot in the 1947 issue of Woman's Day Crochet Annual.
In case you are interested in giving it a geaux (I'm in Louisiana), I've listed the pattern as a Free Download in my shop.
Thanks for dropping by.
