I love a good quick knitting project, and both of these can be whipped up in a day. The twisted necklace is a pattern on Ravelry called Knit Your Pearls. The knotted necklace is called the Gilded Knot Necklace by Nicky Epstein. It was published in Vogue Knitting Winter 2010/11. I was able to use old stash yarn on these (which I love) cause I hate to waste yarn.
