If a designer calls her site "Monster Crochet," she's practically required to have some horror-themed patterns on it. And so it is with Regina Rioux Gonzalez, whose awesome designs you might have seen in magazines like KnitScene and Crochet Today.
Regina's latest pattern is this Bloody Saw Scarf, which I first saw over on Craftster. It's made in a basic, worsted-weight wool yarn: the entire saw portion of the scarf is crocheted in gray, then the "blood" is crochet-embellished on top of it, on the "toothed" edge. Look closely, and you'll see that there are even handles at the ends of the saw!
Some of you will dig it because you're into the Saw horror franchise, others will make it for a horror fan friend, still others will just think this is attractively witty, silly, and/or gross. Whatever your interest in it, you can get the pattern from Regina's site for $5. While you're there, check the sidebar: you might be interested in patterns for her Wearable Web spider-web shawl ($5), her Dem Bones Scarf that looks like connected bones ($5), and her "monster fingers" pattern (free).
