No. It is not allowed to make changes to the layout after the order has been placed. That's why, after you've made all the necessary changes to the template and clicked the "continue" button, the layout confirmation page appears. On this page you can view the layout sketch again. Please note that we don't check and edit the layout. Be careful and check your layout! If all the data is correct and there are no errors, check the layout confirmation box and continue processing the order.
