I finished my latest afghan tonight. I used an "N" size crochet hook and three strands of different colored yarn held together. The yarn I used was Loops and Threads Impeccable Glitter in Mirror, Lion Brand Vanna's Glamour in Rhinestone Pink, and Red Heart Boutique Unforgettable in Winery. The Impeccable yarn is black with multicolored glitter. The Vanna's yarn is a hot pink with pink glitter, and the Boutique yarn is variegated in shades of reds, pinks, and purples.
The stitch I chose is a new one to me but super simple. Like many of the crochet stitches it goes by several names: granite stitch, moss stitch, and woven stitch. Basically it is a single crochet, chain one, single crochet, chain one, and so on all the way back and forth. Here is a good tutorial on how to do it.
Unfortunately the photos don't show how pretty the blanket looks in real life. In these photos it looks much pinker.
And you can't really see the pretty sparkly effect.
