Knitty's Deep Fall issue is now available online, and as always, it's free.
However, the Knitty site has much more to offer than the current issue of the free online magazine. If you are not familiar with Knitty, check out the tabs on the their site - in this issue, knittyspin, pattern library, etc. Looking for a specific designer or pattern from previous issues, use the search feature.
Knitty is published quarterly, and you can receive email notification when the new issue is available by subscribing here.
