From the Pattern Description: Exquisite hand-dyed silk yarn and an open knit make this bag a delicate treasure lined in an iridescent silk dupioni. Quartz beads and tassels give it the extra polish a bride wants. The brioche stitch, which creates a ribbed effect, may take a little getting used to at first. Once you get going, this purse will finish up quickly and look as if you spent a lot of time on it.
