To add items to your favorites, you need to create an account to favorite an image or vendor so we can later retrieve it for you. Otherwise, we wouldn’t be able to tell who favorited what.
When you are viewing a vendor, simply click on the heart icon, to add it to your favorites board. Also, anything under the Attire & Rings category, you can favorite for those items to be added to your Wedding Fashion Board. Your Wedding Fashion board is found by selecting: Planning Tools>Wedding Vision>scroll down to where it says "Keep Tracking Your Favorites." You can find your boards there.
