Before you place your order you can edit your card's thickness and trim (straight or round corners) in 3 places: On the product page before personalizing your card, on the card's Thickness and Trim page which will come up right after personalization before choosing envelope options, or from the Shopping Cart by choosing "Edit Options" from the dropdown below your card.
From the product page
Below the "Personalize" button you'll find a few options for your card. Under the "Paper" dropdown you will be able to choose your paper thickness. Underneath that will be the "Trim" section where you can choose the round or straight corners.
After personalizing
If thickness and trim options are offered for your card format, you will come to a "Thickness and Trim" page after clicking "Next" on the Approvals page of personalization. Choose your thickness on the left and your trim on the right.
In the Shopping Cart
Go to your cart by clicking the shopping cart icon in the top right on any product or category page, then click the "Options" dropdown and choose "Edit Options". This will take you to the Thickness and Trim page where you can choose your options. You'll be taken back through the envelope options (if available) so just click "Next" until you're back at your cart if you have no envelope changes.
If you have already placed your order, you will need to cancel and reorder with the adjusted changes. (See: How do I cancel my order?) If any of these options aren't working or if you have other questions, please contact us and our support team will ensure your order prints with the options you want.
