Hi, log into your Houzz account via the web to do this. Click on the Ideabook you want to share, then click Collaborate. From there, you can type in the email addresses to your friends you want to share the Ideabook with.

On the mobile apps, use the collaborate button to share an ideabook. That button is available when viewing one of your ideabooks, it's also available as a share option in your ideabooks.

If the desktop and mobile don't show you the same ideabooks, are you sure you logged in using the same account on both?

How do I access my friends idea book once they set it up to collaborate

Once an ideabook has been shared with you, you will find it on your profile page along with any ideabooks you have created. Hope that helps!

I set up an ideabook and followed the collaborate steps, but my client can't access it. Is there another step? She set up an account using her same email address. Am I supposed to make the idea book public to share it?
