Once a design has been added to the shopping cart, it becomes locked, and can no longer be edited on the website. If you need major changes, a new product will have to be created. If the change you need is minor, we may be able to do that for you if you notify us***immediately***after placing your order, or include that as a note on the final checkout page. Reaching out directly is the best method, as we will be able to confirm immediately if your request is possible.
