Sidebar add-on?

I’m hoping someone can help me. I hope this is in the right spot too!
I’m looking for a side bar add-on, you can keep track or just show off what you’ve got on the needles or completed. I’ve seen them on other blogs but of course, I can’t find a blog with one now! If you can help, please let me know. Thank you!

I have one on my blog that I downloaded from Ravelry. You have to be a member to have one but membership is free. Just sign up and you’ll get an invite in no time.

Thank you, I am a member of Ravelry. I will look for it!
