Once you've created a Custom Greeting Card purchase option and added it to your storefront, the option will become visible to your clients within their galleries under the Products section.
Clicking on the Greeting Card product will cause the card options to display, and clicking the Create a Design button will start the card editing process.
Upon arriving at the Product Editor your clients will be shown a short tutorial on how to edit their cards. After viewing the tutorial, they will then be given the option to customize their card as follows:
Clicking on the three lines in the upper left corner allows them to choose a Card Design and also Background Colors.
Once a design has been selected, the next step is to add images to the blank image areas within the card design. To add an image to a blank image area, your clients can simply drag the image from the bottom image bar and drop it onto the card. This action will cause a crop selection dialog to appear, where your clients will choose a crop to fit the specific area they've dropped the image onto. Additional images can be dragged into the same image area if they'd like to switch it out.
Your client can also modify any of the editable text by clicking in the text area, and making their changes.
After the front side of the card has been customized, clicking the left or right arrow will take your client to the back side of the card. The design for the back side of the card can be selected similarly to how it was selected for the front side, and the back side's images and text can be customized in the same way as well.
Once your client is happy with their card, they can click the Submit button in the upper right corner to Review and Finalize their card.
Clicking the final Proceed button will add the custom card to their cart and return them to their gallery. If they'd like to modify the design after it's been added to their cart, an Edit Design option is available within the shopping cart page of their gallery.
