CraftForum.com is a free community of crafty people who enjoy making projects and sharing ideas and tips with each other. It doesn’t matter if you’re just getting started or if you’re an old pro, you’ll find the Craft Forum is a great community to join. Best of all it’s totally free!
Most groups I have been on before are ok with posting links to other places - but you can only share the patterns themselves if you own the rights to them.
