Here are the instructions to post a project on Ravelry
1. Click on the link
2. It takes you to the pattern page
3. Click on the "Hook it" icon in the top right area
4. It will let you fill in the blanks, name your own name for the piece you worked. You can name it whatever you want. Example: Donna’s blah blah blah. It will let you rate the pattern also. So you enter all the information about your "project" like, did you like it, did you have to add a round of sc's to make it the right size, what yarn you used etc and then you save that. General notes for other people who will see it.
5. Then there is a tab so you can add your pictures of your square or blanket or multiple squares with the same pattern. It's really kind of easy.
If however, you had already posted the project but didn't know the actual name I was going to title the pattern, you would do steps 1 and 2, highlight the BOLD name that I called the pattern and use this BOLD name in your project you already created and it will link your project to the pattern.
