Ravelry

Ravelry is an amazing resource for Knitters and Crocheters alike. It offers a lot of patterns (both free and pay for) and it helps you organize them all. It is a great place to sell patterns, to buy patterns, and just to organize all your crochet and knitting needs.

You can keep track of your yarn stash on this site, along with all your past, present and future projects. You can add photos, you can visit your library where all your patterns are stored and waiting for you.

You can join a group, start a blog and find almost anything you are looking for on here! They even have a hook and needle tracker for you to use. And the best part it is all free. You only have to pay for the patterns you want; and even some of those are free! And coupons are everywhere if you just look for them.
