Knitty.com is an online knitting magazine based in Toronto and published quarterly since fall 2002.
The magazine was founded by Amy R. Singer and has been edited by her since its inception. Knitty presents free original knitting patterns, essays, and how-to articles written by professional designers and non-professional contributors. It hosts chat forums and promotes the online knitting community, and several patterns, such as Clapotis and Lizard Ridge, have experienced great popularity among knitters. It has also been influential in launching the careers of knitwear designers including Ysolda Teague, Stefanie Japel, Erica Jackofsky, Stephen West, Jillian Moreno, Cookie A, Amy Swenson, Jordana Paige, Cheryl Niamath and many others. The often-cited "Judy's Magic Cast On" and "Jeny's Surprisingly Stretchy Bind off" were first published in Knitty.
Singer has published four knitting-related books.
