Check out this Winter Knit-Along at Lion Brand.
Each season we host a knit- or crochet-along, a virtual event in which yarncrafters come together here online to work on one pattern together, share their experiences, and to learn together.
Fun! And at the end, you'll have the beautiful Inishturk sweater they've chosen for their project. There's a Ravelry group to join and also a Flickr group for posting your photos.
For forums, free patterns, or instructions for a particular technique, nothing beats Knitting Daily. It's where "life meets knitting."
And one of my favorite blogs, one that combines "food, flowers, books, art, yarns and more" (all the good things, in other words) is Cornflower. It's a blog that finds artistry in matching yarn colors to book covers or matching quotations to knitting projects. Beautiful!
So what about you? What's your favorite hobby?
