We want you to receive a great design with a fast turn-around-time, so our team starts working on your 3D space as soon as you've submitted it. For this reason, we don't have the option for you to make changes to your modsy project after you've hit the "Submit Project" button. Rest assured you'll have the option of requesting changes to your design when you receive it.
However, if you have any concerns about your project's details, please email us at firstname.lastname@example.org. A member of our team will be happy to look into the issue and help.
